Crystal structure and magnetism of the binuclear Gd(III) complex Gd-2(C12H8N2)(2)(C6H5COO)(6)

in the medium of H2O, C2H5OH and HAC, the reaction of Gd(NO3)(3). 6H(2)O wi th C6H5COONa and C12H8N2 produced a novel binuclear Gd(III) complex in form ula [Gd-2(C12H8N2)(2) (C6H5COO)(6)]. Crystallographic data: crystal system, triclinic; space group, P (1) over bar; unit cell dimensions, a = 1.191 9( 2) nm, b = 1.244 2(2) nm, c = 1.080 4(2) nm, alpha = 93.57(3)degrees, beta = 113.33(3)degrees, gamma = 105.06(3)degrees, Z = 1. The final R = 0.037 6. The magnetic measurement of the crystal powder in the temperature region o f 1.5-300 K shows that this complex possesses antiferromagnetic property wi th fitting magnetic parameters J = -0.471 and g = 1.975.
