Published: September 2008

In the title complex, [Ni(C(4)N(3))(2)(C(15)H(11)N(3))](n), each of the two different Ni(II) atoms is coordinated by one 2,2':6'2''-terpyridine (terpy) and three tricyano-methanide ligands in a distorted octa-hedral geometry. The Ni(II) atoms are linked to each other, forming an infinite chain parallel to (10). π-π Stacking inter-actions of terpy mol-ecules between adjacent chains (centroid-centroid distance = 3.785 Å), along with weak inter-molecular C-H⋯N hydrogen bonds involving the uncoordinated terminal N atoms of the tricyanomethanide ions and the terpyridine H atoms, result in the formation of a three-dimensional network structure.
