Abstract: The title compound has been synthesized and its crystal structure determined at room temperature. Cd 2 (Sacch) 4 (Im) 4 , F.W. = 1225.83, monoclinic. Space group: C2/c, Z=4, a=20.065(3)1, A, b = 11.164(4) A, c = 20.697(6) A, 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 A.

TL;DR: In this paper, the d-d transition spectrum of the title compound crystal have been determined and it is explained with scaling radial theory of non-free ions which was proposed by our laboratory.
Abstract: Following a recent upsurge of interest in saccharin complexes system, we have synthesized several saccharin mixed ligand complexes and attempt to discussed them. In this work, the d-d transition spectrum of the title compound crystal have been determined and it is explained with scaling radial theory of non-free ions which was proposed by our laboratory. However, the absorption position of d-d transitions of the title compound are at 10474, 12435, 13814, 15627 cm−1. With data in the work of Brown and Shannon, Cu(II)-N bonds of the title compound are discussed and it shows that the coordination ability of saccharin in to copper(II) ion is weaker than that of 2,2′-bipyridine, but more stronger than that of a water molecule.
