Crystal and molecular structure of bis(8-amino-2-methylquinoline)nitratonickel(II) nitrate

Abstract

An X-ray diffraction study of the title compound has been carried out and the structure solved by direct methods. Crystals are monoclinic, space group P2_l/c, Z= 4, a= 15.905(3), b= 8.040(5), _c= 10.736(3)Å, β= 117.78(4)°. The structure was refined by block-diagonal least-squares to R and R′ both 4.2%. The nitrato-group in the cation acts as a bidentate ligand. The presence of the methyl group on the organic ligand produces various distortions of bond lengths and angles, and in the geometrical arrangement about the metal.
