Ligand structures metal-sulfur interactions

A series of 4-methyldithiobenzoate salts of potassium 3, rubidium 4 and cesium 5 show dimeric structures in which each dithiocarboxylate ligand is chelated to two metal cations (Fig. 3) [38]. The two metal atoms are located on the upper and lower sides of the plane involving four sulfur atoms of two dithiocarboxylate ligands. The metal cations further interact with the tolyl fragments in the neighboring molecules. The C-S bond lengths of the potassium...
