Bis(dicyanamido-κN)tetra-kis-(pyridine-κN)nickel(II)

Abstract

In the crystal structure of the title compound, [Ni(C(2)N(3))(2)(C(5)H(5)N)(4)], the Ni(II) cations are coordinated by four pyridine ligands and two dicyanamide anions into discrete complexes. The shortest Ni⋯Ni separation is 8.1068 (10) Å. The structure is pseudo-centrosymmetric and can also be refined in the space group C2/c in which both anionic ligands are strongly disordered and the refinement leads to significantly poorer reliability factors.
