A novel one-dimensional nickel(II) complex with a hydrogen-bond-link

A novel compound [Ni(L)(H2O)(2)](0.5)[Ni(L)(WO4)(2)](0.5). 4H(2)O (1) (L = 3,14-dimethyl-2,6,13,17-tetraazatricyclo[14,4,0(1.18),0(7.12)]-docosane) ha s been structurally and magnetically characterized. The nickel(II) ions are shown to be in distorted octahedral environments with secondary amines of macrocycles in which two trans water molecules and two trans tungstate ions are assembled around each metal center. Two nickel(II) complexes are conne cted into a one-dimensional chain via hydrogen bonds. The magnetic suscepti bility measurement for 1 indicates weak antiferromagnetic interaction (J = -1.01(2) cm(-1); H = -J Sigma S-i. Si+1) between the S = 1 nickel(II) param agnetic centers.
