catena-Poly[[{4-bromo-2-[2-(dimethylamino)ethyliminomethyl]phenolato}copper(II)]-mu-thiocyanato]

The title complex, [Cu(C11H14BrN2O)(NCS)]n, is an interesting thiocyanate-bridged polynuclear copper(II) compound, which crystallizes with two independent molecules in the asymmetric unit. Each CuII atom is five-coordinate in a square-pyramidal configuration, with one O and two N atoms of one Schiff base ligand and one terminal N atom of a bridging thiocyanate ligand defining the basal plane, and one terminal S atom of another bridging thiocyanate ligand occupying the apical position. The {4-bromo-2-[2-(dimethylamino)ethyliminomethyl]phenolato}copper(II) units are linked by the bridging thiocyanate ligands, forming polymeric chains running along the a axis. There are weak intermolecular C-H...O and C-H...S hydrogen bonds between the chains in the crystal structure.
