- The (2 + 1) photoionization mass spectra of Xe-2 molecules are studied in a supersonic jet upon excitation by laser radiation in the energy range 80321.3-77821 cm(-1), corresponding to the dissociation of the Xe-2 molecule into atoms Xe(S-1(0)) + Xe*(6p, 5d). Several vibrational progressions are observed, which are attributed to two-photon transitions of Xe-2 from the ground state to the excited states of the 0(g)(+), 1(g), and 2(g) symmetries. Based on the analysis of these progressions, the molecular constants of a number of excited states of Xe? are estimated.

- Data on excited states of XeKr molecules in the energy range 78280-77600 cm(-1) are obtained. Using the method of multiphoton laser photoionization of molecules in a supersonic jet, five vibrational progressions of XeKr molecules are obtained, which are attributed to five electronic-vibrational transitions from the ground state of the XeKr molecule of the symmetry 0(+) to excited states of the symmetry Omega = 0(+), 1, 2 with the dissociation limit (KrS0)-S-1 + Xe*6p[5/2](2) and of the symmetry Omega = 1, 2 with the dissociation limit Kr + Xe*6p[5/2](3). The molecular constants of the corresponding excited states of the XeKr molecule are estimated.

- The spectra of Xe-2, XeKr, and XeAr molecules in the range 66 500-68 800 cm(-1) are obtained by the methods of (2 + n) and (3 + n) (n = 1, 2, 3) resonance multiphoton ionization during the registration of molecular and atomic ions. The combining of two-and three-photon resonance excitations of Xe-2 molecules makes it possible to obtain the spectra caused by transitions from the ground state X0(g)(+) to the excited states of Xe*6s[3/2](1,2)degrees(XeS0)-S-1 molecules both of the even (0(g)(+), 1(g) ) and of the odd (B0(u)(+), B'1(u) , 2(u) ) symmetries. The data on the Omega = 2(u) state of the Xe-2 molecule with the dissociation limit Xe*6s[3/2](2)degrees + (XeS0)-S-1 and on the Omega = 1 state of the XeAr molecule with the dissociation limit Xe*6s[3/2](1)degrees (ArS0)-S-1 are obtained for the first time. The potential curve of the excited 2(u) state of the Xe*6s[3/2](2)degrees (XeS0)-S-1 molecule is repulsive and intersects the potential curve of the B0(u) + state of the Xe*6s[3/2](1)degrees (XeS0)-S-1 molecule. In the case of the three-photon excitation, it is observed that all the bands in the spectra of XeKr and XeAr molecules are broadened and are shifted, which indicates that, in an intense light field, the influence of the dynamic Stark effect is significant.

- The reaction of [Ru-3(III) (mu(3)-O)(mu-O2CCF3)(6)(H2O)(3)](O2CCF3) in methanol gives two solvates, [Ru3O(O2CCF3)(6)(DMSO)(3)] center dot 1/2H(2)O (I) and [Ru3O(O2CCF3)(6)(DMSO)(3)] center dot H2O (II), of a novel trinuclear mixedvalence Ru(II,III,III) trifluoroacetate complex, where two DMSO molecules are coordinated to the Ru atoms through the O atom, while the third DMSO molecule is coordinated through the S atom. According to the X-ray diffraction data, the complex can crystallize in two crystal systems: triclinic (I) (space group P (1) over bar) and monoclinic (II) (space group P2(1)/m). The unit cell parameters for I are: a = 9.354, b = 11.005, c = 20.846 angstrom, alpha = 99.10, beta = 96.38, gamma = 92.17, Z = 2; R = 7.27%; for I are: a = 9.186, b = 17.044, c = 13.091 angstrom, beta = 101.10, Z = 2; R = 14.18%.
