Crystal structure and magnetism of the binuclear Gd(III) complex Gd2(C12H8N2)2(C6H5COO)6

Abstract

In the medium of H2O, C2H5OH and HAC, the reaction of Gd(NO3)3·6H2O with C6H5COONa and C12H8N2 produced a novel binuclear Gd(III) complex in formula [Gd2(C12H8N2)2 (C6H5COO)6]. Crystallographic data: crystal system, triclinic; space group, P1; unit cell dimensions, a=1.191 9(2) nm,b =1.244 2(2) nm,c = 1.080 4(2) nm, α = 93.57(3)°, β= 113.33(3)°, γ= 105.06(3)°, Z=l. The finalR =0.037 6. The magnetic measurement of the crystal powder in the temperature region of 1.5–300 K shows that this complex possesses antiferromagnetic property with fitting magnetic parametersJ = −0.471 andg =1.975.
