The asymmetric unit of the title compound, [Co(C(9)H(8)Cl(2)NO)(3)], contains three independent mol-ecules. In each mol-ecule, the Co(III) ion is coordinated by an O atom and an N atom from three bidentate 2,4-dichloro-6-(ethyl-imino-meth-yl)phenolate ligands in a slightly distorted octa-hedral environment. In the crystal, a weak C-H⋯Cl hydrogen bond is(More)
The title complex, [Co(C(10)H(9)N(4)O(2)S)(2)(C(3)H(7)NO)(2)], lies across an inversion center. The Co(II) atom is coordinated in a slightly distorted octa-hedral geometry by four N atoms from two bidentate 4-amino-N-(pyrimidin-2-yl)benzene-sulfonamidate (sulfadiazine) anions and two O atoms from two dimethyl-formamide (DMF) ligands. The dihedral angle(More)
In the title complex, [Ni(C(9)H(9)BrNO)(2)], the Ni(II) ion lies on an inversion centre and is coordinated in a slightly distorted square-planar geometry by two N atoms and two O atoms from two symmetry-related bidentate 4-bromo-2-(ethyl-imino-meth-yl)phenolate ligands. The complex forms a one-dimensional chain in the crystal structure through short C-H⋯Br(More)
