Abstract
As novel molecule-based magnetic materials based on metal coordination polymers bridged by bim2-, [(Ni-cyclam)2(bim)](ClO4)2 (1) (bim2- = dideprotonated 2,2′-biimidazolate dianion) was synthesized and the crystal structure was characterized by X-ray crystal analysis. (Crystal data: orthorhombic, Pbca (No. 61), a = 16.677(2) Å, b.= 16.447(5) Å, c = 13.212(1) Å, V = 3623(1) Å3, Z = 4) The magnetic susceptibility measurements of the dinuclear nickel (II) complex (1) in the crystalline state showed the weak antiferromagnetic property (J= − 4.6 cm−1), which was also sujested by the ESR mesurements.
