- Powders of the zinc and copper(II) dimethyl- (MDtc), diethyl- (EDtc), and morpholinedilhiocarbamate (MfDtc) complexes quantitatively absorb hexamethyleneimine (Hmi) to produce the adducts [M{NH(CH2) 6}(S2CNR2)2] (M = Zn, Cu; R = CH3, C2H5; R2 = (CH 2)4O). The heterogeneous reaction of adduct formation is accompanied by dissociation of the binuclear molecules [M2(DtC) 4] of the initial dithiocarbamate complexes. Computer-aided simulation of EPR spectra for the copper(II) adducts shows that they are individual. The coordination polyhedron of copper in these compounds is intermediate between a trigonal bipyramid (TBP) and a square pyramid (SP). Based on EPR data, the TBP contribution is quantitatively estimated. 13C and 15N NMR shows that the MDtc and EDtc ligands in the adducts are structurally nonequivalent, whereas the MfDtc ligands are structurally equivalent. The 15N isotropic chemical shifts of the dithiocarbamate groups depend on alkyl substituents at the nitrogen atom.
