Reactions of [ReOCl3(PPh3)2] with an equimolar amount of iPr2NCS2Na or an excess of Et2NCS2Na in a mixed solvent of chloroform and methanol produced a mononuclear oxorhenium(V) complex [ReOCl2(S2CNiPr2)(PPh3)] (4) and a dinuclear oxorhenium(V) complex [Re2O3(S2CNEt2)4]

Tris (N,N-diisopropyldithiocarbamato)- complexes of the type CpM(S2CN i-pr2)3 and (MeC5H4)M(S2CN i-pr2)3 (where M = Ti, Zr), have been prepared by the reaction of Cp2MCl2 or (MeC5H4)2MCl2 with anhydrous Na(S2CN i-pr2) in refluxing CH2Cl2 or THF. Conductivity measurements and molecular weight determinations indicate that these complexes are monomeric and nonelectrolytic. On the basis of the IR spectra
Di-alkyl tin(IV) bis-dithiocarbamato complexes of the type R2Sn(IV)[R′R″dtc]2 or R2Sn(IV)[morph. dtc]2 (where R = n-Bu, n-Hex, R′ = R″ = Me, Et, i-Pr; R′ = Me and R″ = Ph) have been prepared by the reaction of di-n-butyl or di-n-hexylSn(IV) dichloride with the sodium salt of respective dithiocarbamic acid in 1:2 molar ratio in dry acetone. The IR, 1H NMR and Mossbauer studies indicate an anisobidentate

Reactions of dibromodioxobis(dimethylsulfoxide)molybdenum(VI) with sodium/potassium salts of N,N′-dialkyl dithiocarbamates or O-alkyl dithiocarbonates in 1:1 molar ratio in dichloromethane yield bromodioxomolybdenum(VI) complexes of the type, MoO2Br(S2CNR2)(OSMe2) (R = Et, Prn, Pri) or MoO2Br(S2COR)(OSMe2) (R = Et, Prn, Pri). These newly synthesized complexes were characterized by elemental analysis
