Abstract
The compound [Cu(NH2CH2C6H4N=CHC5H5N)Cl2] (1) containing the tridentate Schiff base ligand, which is the 1:1 condensation product of pyridine- 2-carboxaldehyde and 2-amino benzyl amine, was synthesised and its crystal structure has been determined. It is monomeric, space group P1, a = 7.704(1), b = 9.308(2), c = 11.228(2) A˚ , α= 68.97(2), β= 82.23(1), γ= 67.70(1)° and Z = 2. The crystal structure of 1 is based on a five coordinate copper centre with trigonal bipyramidal geometry. The six membered chelate ring possesses a half-chair conformation with C7 most out of the plane made by Cu1, N2, N3, C8 and C9. There is a hydrogen bond between Cl2 and an amine hydrogen H2A of a neighbouring molecule related by a centre of inversion
