Synthesis,Crystal and Molecular Structure of Cd2(sacch)4(Im)4

The title compound has been synthesized and its crystal structure determined at room temperature. Cd₂(Sacch)₄(Im)₄ F.W. = 1225.83, monoclinic. Space group: C2/c, Z = 4, a = 20.065(3) Å, b = 11.164(4) Å, c = 20.697(6) Å, β = 94.69(5)°, The coordination polyhedron of Cd(II) correspond to a five-coordinate trigonal-bipyramid. In the title complex, two of the saccharin groups act as monodentate ligands. The other two act as bidentate ligands. The two Cd(II) ions are bridged by the two bidentate saccharin groups and the distance is 4.75 Å.
