Isothiocyanatooxomolybdenum(V) complexes, [MoO-(NCS)(R2dtc)2] (R=ethyl or dibenzyl; R2=piperidinyl or 4-morpholinyl) have been prepared and characterized. The i.r. spectral bands at 2020 cm-1 are assigned to v(CN) which suggest that thiocyanate coordinates through nitrogen. The bands at 930, 1500 and 960 cm-1 are attributed to v(MoO), v(CN) and v(CS), respectively, and indicate the presence of the MoO3+ moiety and a bidentate dithiocarbamate group. The e.p.r. and electronic spectral data together with magnetic moment values (1.69 B.M.) suggest the presence of one unpaired electron. The complexes are monomeric. The thermal decomposition behaviour of the complexes is reported. © 1984 Verlag Chemie GmbH.

Isothiocyanatooxomolybdenum(V) dithiocarbamates

Transition Metal Chemistry

The interaction of H2S gas with aqueous ammonium heptamolybdate solution in the presence of diethylenetriamine (dien) led to the formation of diethylenetriammonium tetrathiomolybdate crystals. The elemental analyses, UV-Visible, IR, and 1H NMR spectra suggested the presence of organic cation and (MoS4)2- moiety. The 1H NMR revealed the presence of two sets of symmetrical A2X2 multiple patterns. The compound crystallizes in the monoclinic system with space group Pn, a = 7.196(6), b = 7.532(3), c = 11.525(10) Å, α = 90°, β = 90.17(3)°, γ = 90°, V = 624.78(8) Å3, and Z = 2, wR1 = 0.0261 and wR2 = 0.0698. The structure consists of tetrahedral tetrathiomolybdate anions, which form an extended three-dimensional network in the solid state with Mo-S⋯H-N hydrogen bonding with the organic cation.
