The Coordination Chemistry of Imidomethanedithiolate Di-anions: A Structural Comparison with Their Dithiocarbamate Analogs

A review of the coordination chemistry along with structural features heavy element complexes dithiocarbimate di-anions in form [(R)C=NCS2]2− for R = CN, alkyl, and aryl are described. This class compound is far less studied compared well-explored dithiocarbamate mono-anions formulated as [R(R’)NCS2]− R/R’ H, aryl. The dominated by a S,S-chelating mode; rare examples alternative modes evident. When comparisons available, motifs adopted metal match those found their analogs, only small, non-systematic variations M–S bond lengths.
