TL;DR: In this article, metal(II) complexes of N-(thiophene-2-carboxamido)salicylaldimine (H2TCS) of types M(HTCS)-2Cl2 [M = Ni, Cu, Zn, Co, Ni and Zn] have been prepared and different modes of chelation of the ligand and the stereochemistry of the complexes are discussed.

TL;DR: In this article, isomaleonitrile dithiolates of the types M(i-MNT) and K2[M(II), Cd(II, or Hg(II) were characterized on the basis of analytical data, molar conductance, molecular weight, infrared and X-ray diffraction measurements.
Abstract: Isomaleonitrile dithiolates of the types M(i-MNT) and K2[M(i-MNT)2][M = Zn(II), Cd(II) or Hg(II); i-MNT = isomaleonitrile dithiolate (S2C:C(CN)2)2-] and their reaction products with ethylenediamine (en) have been isolated and characterized on the basis of analytical data, molar conductance, molecular weight, infrared and X-ray diffraction measurements. Tetrahedral coordination around M(II) in M(i-MNT), K2[M(i-MNT)2] and Zn(en) (i-MNT) and octahedral codrdination around M(II) in the other complexes has been proposed.

TL;DR: The 2-thenoylhydrazine, TH(L) (Fig. 1) complexes having 1:1, 1:2 or 1:3 metal-ligand stoichiometry have been prepared and characterized by elemental analyses, molar conductance, molecular weight, magnetic susceptibility, electronic, infrared, NMR, Mossbauer and X-ray powder diffraction studies as mentioned in this paper.
Abstract: The 2-thenoylhydrazine, TH(L) (Fig. 1) complexes having 1:1, 1:2 or 1:3 metal-ligand stoichiometry have been prepared and characterized by elemental analyses, molar conductance, molecular weight, magnetic susceptibility, electronic, infrared, NMR, Mossbauer and X-ray powder diffraction studies. Tetrahedral stereochemistry around Zn(II), Cd(II) and Hg(II), square pyramidal geometry around VO(IV) and octahedral coordination around Mn(II), Fe(II), Co(II), Ni(II) and Cu(II) ions have been proposed in these complexes on the basis of magnetic and spectral studies.
