Özet
The title complex, [CdNi(CN)4(C6H7N)2]n, adopts a slightly distorted octahedral geometry around the Cd centre. Four cyanide N atoms occupy the equatorial coordination sites around the Cd centre. The structure consists of corrugated and cyanide‐bridged polymeric networks made up of tetracyanonickelate ions coordinated to cadmium, with the Ni ion coordinated by four cyanide ligands in a square‐planar arrangement. The Cd and Ni atoms occupy special positions of 2/m site symmetry. The 3‐methylpyridine group, except for two methyl H atoms, lies on a crystallographic mirror plane. The 3‐methylpyridine molecules, bound to cadmium 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 atoms.
