Abstract

Two new binuclear nickel(II) complexes [Ni₂L₂(NCS)₂](ClO₄)₂ (1) and [Ni₂L₂(NCO)₂](ClO₄)₂ (2), where L is a pentadentate Schiff base ligand derived from the reaction of 2 mol of 2-benzoyl pyridine and 1 mol of diethylene triamine, have been prepared and characterized. The structures of complexes 1 and 2 have been studied by single crystal X-ray diffraction analysis. The structure analysis reveals that each nickel(II) center is coordinated in a distorted octahedral (NiN₆) fashion consisting of three nitrogen atoms from one and two nitrogen atoms from other pentadentate ligand and the last one from terminal thiocyanato/cyanato ion. The variable temperature magnetic susceptibility of both compounds 1 and 2 have been studied and found a very weak magnetic interaction between two nickel(II) centers consistent with the structures (Ni⋯Ni distance of 5.809(l) Å for 1 and 5.695(l) Å for 2 with no suitable bridge or linkage to propagate magnetic interaction).
