چکیده
The title dinuclear copper(II) complex [Cu2(C18H16Br2N2O4S2)2] was prepared by direct synthesis of a dianionic Schiff base derived from 5-bromo-salicyl-aldehyde and cyste-amine. The discrete mol-ecules lie across inversion centers and crystallize with two di-methyl-formamide (DMF) mol-ecules of crystallization. The unique CuII ion is four-coordinated by two tetra-dentate Schiff base ligands in a distorted square-planar N2O2 environment. In the crystal, short inter-molecular S⋯Br contacts, weak C-H⋯O hydrogen bonds and intra- and inter-molecular π-π stacking inter-actions between rings of the ligand link the components into a two-dimensional network parallel to (010).

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 contacts (H⋯Br = 3.009 Å).

It is demonstrated here that tridentate imine ligands can control the nuclearity of copper(II) complexes based on the donor atoms present in the ligand. The N,N',N''-donating imine ligand led to a mononuclear compound, namely di-chlorido-[N,N-dimethyl-N'-(pyridin-2-yl-methyl-idene)ethane-1,2-di-amine]copper(II) monohydrate, [CuCl2(C10H15N3)]·H2O, 1, while the N,N',O-donating imine ligand produc...
