Bis(tetrabutylammonium) bis(3,4,5-trioxocyclopent-1-ene-1,2-dithiolato-κ2S,S′)cadmate(II) 0.25-hydrate

The title compound, (C16H36N)2[Cd(C5O3S2)2]·0.25H2O, contains two disordered tetrabutylammonium cations, a complex [Cd(C5O3S2)2]2− anion and a 0.25-hydrate water. The anion is composed of a bidentate coordinated 3,4,5-trioxocyclopent-1-ene-1,2-dithiolate (dtcroc) group forming a distorted tetrahedral configuration around the CdII ion. The dihedral angle between the least-squares planes of the ten-atom sulfur-substituted croconate groups in the anion is 84.10 (8)°. The crystal packing is stabilized by weak C—H...O and C—H...S cation–anion hydrogen-bond interactions. In each of the two cations one butyl group is disordered over two positions in the ratios 0.589 (11):0.411 (11) and 0.796 (12):0.204 (12).
