Four metal complexes of dibenzyl dithiocarbamate [Cd (DBTC) 2] 2 (1), [Hg (DBTC) 2] (2), [Nd (DBTC) 3 · 2H 2 O] The synthesis and infrared spectra of Nd (DBTC) 3 (HMPA) 2] (DBTC = N, N dibenzyldithiocarbamic acid and HMPA = hexamethylphosphoramide) The crystal structure was confirmed by X-ray crystallography. Complex 1, C3 0 H2 8N2 CdS4, Mr = 65 7.18, monoclinic system, space group P2 1 / n, a = 1.11098 (4) nm, b = 1.563 2 5 (5) nm, c = 1.66695 (5) nm, β = 97.92 2 0 (10) °, Z = 4, R = 0.044, wR1 = 0.091.2, C3 0 H2 8N2 HgS4, Mr = 745 3 7, orthorhombic space group Pbcn, a = 1.64 73 8 (1) nm, b = 1.864 18 (14) nm, c = 0.940 0 0 (6) nm, Z = 4, R = 0 0 3 87, wR1 = 0 0 965 .3, C57H78N9NdO2 P2 S6, Mr = 13 19.82, monoclinic space group P2 1 / c, a = 1.3 0 3 89 (9) nm, b = 3 .470 8 (3) nm, c = 3.12 10 (2) nm, β = 96.5 2 7 (2) °, Z = 8, R = 0.10 2 3, wR1 = 0.2203. 1 is a dimer, the coordination structure of the central ion is a distorted tetragon; 2 and 3 are mononuclear complexes, but the coordination structure of the central ion is different, 2 is a distorted tetra While the third is the deformed dodecahedron.The thermogravimetric analysis of the complexes showed that complexes 1 and 2 may be accompanied by sublimation in the process of weightlessness heating and are expected to be precursors of MOCVD
