Bis[N-(2-hydroxyethyl)-N-isopropyldithiocarbamato-κ2S,S′](piperazine-κN)cadmium: crystal structure and Hirshfeld surface analysis

Abstract

The title compound, [Cd(C6H12NOS2)2(C4H10N2)], features a distorted square-pyramidal coordination geometry about the central CdIIatom. The dithiocarbamate ligands are chelating, forming similar Cd—S bond lengths and define the approximate basal plane. One of the N atoms of the piperazine molecule, which adopts a chair conformation, occupies the apical site. In the crystal, supramolecular layers propagating in theacplane are formedviahydroxy-O—H...O(hydroxy), hydroxy-O—H...N(terminal-piperazine) and coordinated-piperazine-N—H...O(hydroxy) hydrogen bonds; the layers also feature methine-C—H...S interactions and S...S [3.3714 (10) Å] short contacts. The layers stack along theb-axis direction with very weak terminal-piperazine-N—H...O(hydroxy) interactions between them. An evaluation of the Hirshfeld surfaces confirms the importance of intermolecular interactions involving oxygen and sulfur atoms.
