ZnL2(NO3)2, ZnL2(ClO4)2, CdL2Cl2, and HgL2Cl2 were obtained by mixing aq. solns. of thiosemicarbazide (L) and the corresponding salts in a 2:1 molar ratio. By elemental anal. and ir spectral studies, the metal ion in the thiosemicarbazide complexes is coordinated through the S and the N atoms of the hydrazinic residue; the ligands in these complexes are arranged in a tetrahedral manner. The complexes were also characterized by uv spectra and cond. measurements. [on SciFinder(R)]

Metal Sulfide Synthesis by Self-Propagating Combustion of Sulfur-Containing Complexes
Coordination compounds of thiourea with cadmium(II), zinc(II), bismuth(III), and indium(III) nitrates were synthesized. The self-sustained combustion of these complexes, as well as that of
Crystal structure of the Zinc(II) nitrate complex with thiosemicarbazide [Zn(NH2NHC(=S)NH2)2](NO3)2
Recently, a new method for the synthesis of metal sulfides was suggested; it is based on combustion of the precursors of these compounds metal nitrate complexes with energy sulfur-containing ligands,
Synthesis and Characterization of Rhodium (III), Iridium(III), Palladium(II) and Platinum(II) Complexes of Cyclohexanone Thiosemicarbazone
Abstract A series of cyclohexanone thiosemicarbazone complexes of the general compositions, M(ligand)3X3 and M(ligand-H)3, M = Rh(III), Ir(III), × = Cl, Br or I and M(ligand)2X2 and M(ligand-H)2, M =
The influence of the chelate effect on supramolecular structure formation: synthesis and crystal structures of zinc thiourea and thiosemicarbazide complexes with terephthalate
The lability of the ligand with a potential hydrogen bond donor–hydrogen bond donor arrangement was found to be the predominant factor in determining the structures of the adducts formed between
