Poly[bis[μ-1,4-bis(imidazol-1-yl)butane]dicyanatonickel(II)]

Abstract

The coordination geometry of the Ni II atom in the title complex, [Ni(NCO) 2 (C 10 H 14 N 4 ) 2 ] n or [Ni(NCO) 2 (bimb) 2 ] n , where bimb is 1,4-bis(imidazol-1-yl)butane, is distorted octahedral, in which the Ni II atom lies on an inversion centre, coordinated by four N atoms from the imidazole rings of four symmetry-related bimb ligands in the equatorial positions and two N atoms of two symmetry-related NCO − ligands in the axial positions. The Ni II atoms are bridged by four bimb ligands to form a two-dimensional (4,4)-network.
