Structural and spectroscopic characterization of bis(thiosaccharinato)bis(benzimidazole)cadmium(II)

The crystal structure of [Cd(tsac)2(bzim)2]·CH3OH (tsac, anion of thiosaccharine; bzim, benzimidazole) has been determined by single crystal X-ray diffractometry. It crystallizes in the triclinic space group P1¯ with Z = 2. The Cd(II) cation is in a distorted tetrahedral environment coordinated to two thiosaccharinate anions [Cd–S bond lengths of 2.5117(6) and 2.5598(6) Å] and two benzimidazole molecules [Cd–N lengths of 2.235(2) and 2.256(2) Å]. The FTIR spectrum of the complex is also recorded and briefly discussed. Some comparisons with related complexes are made.
