The title complex Ni(C4H5NO4)(C7H6N2)3·1.75(H2O)(C25H26.5N7NiO5.75,Mr=575.74) has been prepared and its crystal structure was determined by X-ray diffraction method.The crystal of this chiral complex belongs to monoclinic,space group P21 with a=13.208(1),b=10.741(1),c=19.398(1)A,β=104.39(1)°,V=2665.8(4)A3,Z=4,Dc=1.435 g/cm3,μ(MoKα)=0.780 mm-1 and F(000)=1198.The final R=0.0504 and wR=0.1267 for 9159 observed reflections (I>2σ(I)),and R=0.065 and wR=0.1299 for 11006 independent reflections.The complex assumes a distorted octa-hedral coordinate geometry formed by one aspartate dianion and three benzimidazole ligands.The aspartate chelates to the Ni atom as a tridentate ligand.The lattice water molecules are hydrogen-bonded to the Ni complex molecule.
