Crystal structure of caesium tetramethyldithioimidodiphosphinate

Abstract

In the title crystal, the salt [CsMe 2 P(S)NP(S)Me 2 ] is self-assembled as an undulating supramolecular two-dimensional polymeric structure, poly[(μ 4 -tetramethyldithioimidodiphosphinato)caesium], [Cs(C 4 H 12 NP 2 S 2 )] n , which is parallel to the bc plane. The Cs cations are hexacoordinated, being chelated by two thioimidophosphinate groups and two sulfur atoms from neighboring ligands. The anions are linked to the Cs cations by Cs...S and Cs...N electrostatic interactions.
