Crystal and molecular structure of catena-µ-isothiocyanato-(N′-pyridylmethylene-N″-salicyloylhydrazinato-NN′O)copper(II)
Abstract
The crystal structure of the title compound has been determined by three-dimensional Patterson and Fourier methods from X-ray diffractometer data. Crystals are monoclinic, a= 16.46(1), b= 15.72(1), c= 5.63(1)Å, β= 92.4(1)°, Z= 4, space group P21/n. The structure was refined by least-squares to R 4.1 for 2 087 observed reflexions. Co-ordination around the metal is distorted square pyramidal and involves one organic anion, which chelates through the carbonyl oxygen [Cu–O 1.990(3)Å], a hydrazine nitrogen [Cu–N 1.925(4)Å], and a pyridine nitrogen [Cu–N 2.038(3)Å], and a thiocyanate nitrogen [Cu–N 1.930(5)Å] and sulphur [Cu–S 2.709(2)Å] from an adjacent thiocyanate group. This group bridges the co-ordination polyhedra in zig-zag chains along [001].
