摘要：

The crystal structure of bis(2,2':6',2 ''-terpyridine)nickel(II) bis(perchlorate) hydrate has been determined by single-crystal X-ray diffractometry. The compound is monoclinic, space group P2(1), with two molecules in a unit cell of dimensions a 8.827(4), b 8.910(2), c 20.148(9) Angstrom, beta 98.71(2)degrees. The structure was refined by least-squares to a residual of 0.065 for 2184 observed reflections. The compound is found to be isomorphic with the iron(II) analogue previously reported: the cation has approximate D-2d symmetry, with the main distortion from octahedral symmetry being an axial compression. Both the solid state reflectance and solution spectra have been measured and some significant differences are noted.
