SYNTHESIS, CRYSTAL STRUCTURE, MAGNETIC PROPERTIES AND THERMAL STABILITY OF GD(REO4)3(H2O) 3

Trisaquatris(tetraoxorhenate(VII)) gadolinium(III), Gd(ReO4)3(H2O) 3, was prepared by the reaction of Gd2O3 with HReO4 at room temperature. The colorless compound crystallizes in the orthorhombic space group Pna21 (No. 33) with four formula units per unit cell (a = 1470.9 pm , b = 843.6 pm, c = 1146...
