- A new mu-phenoxy-mu-metoxy di-manganese(III) complex with the trisphenolic ligand, 2,6-bis[((2-hydroxybenzyl)(2-pyridylmethyl)amino)methyl]-4-methylphenol, was isolated as a perchlorate salt. The X-ray structure shows that the two manganese(III) ions are in a distorted octrahedral enviroment with approximately perpendicular Jahn-Teller axes. Investigation of the molar magnetic susceptibility reveals a ferromagnetic coupling between the two high-spin manganese(III) ions. Fitting of the data led to g = 2 and J = 12.5 cm(-1).

Journal article (peer-reviewed)abstract
- The modern lifestyle has driven the advent of high-power electronic gadgets to need high-efficiency energy storage devices. Towards that goal, reduced graphene oxide (rGO) mediated polyoxometalates (POMs) based electrode materials are increasingly showing promising performance for building efficient energy storage devices primarily due to their redox properties. In this report, the silicotungstate [K5[SiVW11O40]. nH2O (SiVW11) embedded rGO nanocomposites as electrode materials in supercapacitor applications were synthesized via chemical and hydrothermal methods. The synthesized nanocomposites were characterized by various techniques, such as Fourier-Transform-Infrared (FTIR) Spectroscopy, Powder X-ray Diffraction (XRD) and Energy Dispersive X-ray Spectroscopy (EDS), Thermogravimetric Analysis (TGA), X-ray photoelectron spectroscopy (XPS) and Brunauer-Emmett-Teller (BET) measurement. The nanocomposites electrochemical properties were examined by adopting a two-electrode setup with cyclic voltammetry (CV) and galvanostatic charge/discharge (GCD) in a 0.5 M H2SO4 electrolyte medium. The hydrothermally reduced graphene oxide (HrGO) nanocomposite exhibited a noticeable surge in areal capacitance of 377.4 mF/cm2 at a current density of 1.5 mA/cm2. The resulting composite had 52.4 & mu;Wh/cm2 and 1500 & mu;W/cm2 as energy and power density, respectively at 1.5 mA/cm2 current density. In addition, the capacitance retention is over 81% after 5000 cycles at a current density of 9 mA/ cm2. The highest specific power of 5000 & mu;W/cm2 was obtained at 5 mA/cm2 current density. On the other hand, chemically reduced graphene (CrGO) nanocomposite showed an areal capacitance of 277.2 mF/cm2 at the same current density. As a result, the SiVW11 clusters coupled with the rGO increase the areal capacitance of nanocomposites with exceptional electrical and mechanical stability. From an application standpoint, both composites were employed successfully for running a DC motor in a series cell connection.

Network analysis of barium oxalates Ba(C2O4)m(HC2O4)n(H2C2O4)p(H2O)q, including the new, uniform, five-connected loh net

In: Inorganic Chemistry Communication. - : Elsevier BV. - 1387-7003. ; 12:2, s. 105-108

Journal article (peer-reviewed)abstract
- The structures of three compounds from the system Ba(C2O4)m(HC2O4)n(H2C2O4)p(H2O)q have been structurally reinvestigated by low-temperature X-ray diffraction. Ba(C2O4)(H2O)2, 1, Ba(C2O4)(H2C2O4)(H2O)2, 2, and Ba(C2O4)0.5(HC2O4)(H2O), 3. The compounds are composed of three-dimensional coordination network structures with bridging oxalates and water molecules. Compound 1 is binodal, four and five connected with topology (4462)(4466)-tcs; 2 contains the common 66-dia net and 3 displays the new uniform network topology 610-loh. Together with the recently reported 610-ghw and 610-rld-z nets, and the 610-fnu net, the loh net forms a subclass of five-connected 610-nets based on the distorted trigonal bipyramidal coordination.

Green-emitting manganese (II) complexes with phosphoramide and phenylphosphonic diamide ligands
- 2018
-
In: Inorganic Chemistry Communications. - : Elsevier. - 1387-7003 .- 1879-0259. ; 92, s. 145-150
-
Journal article (peer-reviewed)abstract
- Tetrahedral manganese(II) complexes having formulae [MnX2{O = PR(NMe2)2}2] (X = Br, I; R = NMe2, Ph) were isolated and characterized, and in the case of [MnBr2{O = PPh(NMe2)2}2] the structure was ascertained by means of single crystal X-ray diffraction. All the complexes showed intense green emission assigned to the Mn(II) 4T1(4G) → 6A1(6S) transition upon excitation with UV light, with photoluminescence lifetimes in the range 100–1000 μs. Bromo-complexes maintain their luminescence features once dispersed in polycaprolactone matrix.

Journal article (peer-reviewed)abstract
- The Cu(I) coordination polymer [Cu3(μ3-I)3(μ-btzMe)(NCCH3)]n (btzMe = 1-methyl-1H-benzotriazole) was prepared and characterized by X-Ray diffraction. The compound showed strong green emission upon excitation with wavelengths below 475 nm, with lifetime of 47 μs. The emission was attributed to 3(X,M)LCT transition on the basis of experimental data and DFT calculations.

Journal article (peer-reviewed)abstract
- Herein, we report the synthesis of two hybrid compounds based on decavanadate anion, namely, [Cu(dien)(Hdien)]2[V10O28]·2H2O (1) and (H3dien)2[V10O28]·4H2O (2), where dien = diethylenetriamine, obtained under mild conditions. Both compounds were characterized by elemental, TG/DTA, single crystal and powder X-ray diffraction analyses, IR and EPR spectroscopies. The compound 1 was found to be active as homogeneous photochemical oxidation catalyst of water to dioxygen.

- 2020
-
In: Inorganic Chemistry Communications. - : Elsevier. - 1387-7003 .- 1879-0259. ; 116
-
Journal article (peer-reviewed)abstract
- The cationic Cu(I) complex [Cu(N^N)2]+, where N^N is bis(indazol-1-yl)phenylmethane, was synthesized as chloride or tetrafluoroborate salt by reacting CuCl or [Cu(NCCH3)4][BF4] with bis(indazol-1-yl)phenylmethane under mild conditions. The structure of [Cu(N^N)2]Cl was ascertained by single-crystal X-ray diffraction. The complex exhibited bright yellow emission upon excitation with near UV and violet light, attributed to triplet LLCT/MLCT transitions on the basis of experimental data and computational outcomes.

Modification of electron transfer properties in photoelectrochemical solar cells by substituting {Ru(terpy)(2)}(2+) dyes with thiophene
- 2004

In: Inorganic Chemistry Communications. - : Elsevier BV. - 1387-7003 .- 1879-0259. ; 7:1, s. 117-121
-
Journal article (peer-reviewed)abstract
- A comparison of the properties of the 2-thienyl-substituted carboxyphenyl {RuII(terpy)2} dyes with their non-substituted analogues has enabled us to gain insight into the electronic properties that are prerequisite for efficient electron injection into the TiO2 conduction band in photoelectrochemical solar cells. Introducing the thienyl group has a profound effect upon the efficiency of photoinduced electron injection. This effect can be explained by a significant shift in the LUMO position from the terpy ligand anchored on the TiO2 surface towards the 2-thienyl substituted ligand, which is shown by means of electrochemistry and semiempirical calculations.
