[(NI(3,2,3-TET)(MU-NCO))N](CLO4)N - STRUCTURAL CHARACTERIZATION OF THE 1ST MONODIMENSIONAL NICKEL(II)-CYANATO SYSTEM WITH A DESCRIPTION OF ITS FERROMAGNETIC COUPLING

The title compound has been characterized by means of X-ray crystallography. The cyanato ligand acts as a bridge between the square planar [Ni(3,2,3-tet)]2+ entities (3,2,3-tet = N,N'-bis(3-aminopropyl)-1,2-ethanediamine), giving an unprecedented chain structure. Crystal data for [{Ni(3,2,3-tet)(mu-NCO)}n](ClO4)n: FW = 374.47, monoclinic, space group P2(1)/n, a = 10.587(2), b = 12.395(2), c = 11.871(2) angstrom, beta = 92.00(1)-degrees, Z = 4, D(c) = 1.597 g cm-3, R = 0.038, R(w) = 0.041. The magnetic susceptibility data indicate weak ferromagnetic coupling.
