Structure of bis(4-methyl pyridine) cadmium tetracyanonickelate

Abstract

The structure, C16H14CdN6Ni, consist of corrugated polymeric networks made up of tetracyanonickelate ions coordinated to Cd. The 4-methyl pyridine molecules bound to Cd in trans positions are located on both sides of the network. The bonding in the networks occurs because of a departure of the Ni-C-N-Cd sequence of atoms from linearity at the C and N positions. The crystal structure of the title compound was determined as monoclinic by single crystal X-Ray diffraction technique. The crystal parameters of this compound are as follows: monoclinic C2/m, a=18.156(2) Angstrom, b=7.581(2) Angstrom, c=6.983(2) Angstrom, beta = 110.09(2)degrees, V=902.6(5) Angstrom(3), Z=2, Dr = 1.698 g/cm(3), F(000) = 456, lambda (MoK alpha) = 0.71070 Angstrom, mu = 2.121 mm(-1). The structure was solved by SHELXS-86 and refined by SHELXL-93. R = 0.02 for 1074 observed reflections with I > 2 sigma(I).
