Crystal structure of dipotassium N-carbodi-thio-ato-l-prolinate trihydrate.

ABSTRACT: The mol-ecular and crystal structure of the l-proline-derived di-thio-carbamate-carboxyl-ate compound poly[tri-μ-aqua-(μ-2-carboxyl-atopyrrolidine-1-carbodi-thio-ato)dipotassium], [K₂(C₆H₇NO₂S₂)(H₂O)₃] _n or K₂(SSC-NC₄H₇-COO)·3H₂O, has been determined. The di-thio-carbamate moiety displays a unique coordination mode, comprising a 'side-on' π-coordinated K⁺ cation besides a commonly σ-chelated K⁺ cation. By bridging coordination of the CSS group, COO group and water mol-ecules, the K⁺ cations are linked into a two-dimensional coordination polymer extending parallel to the ab plane. These layers are again inter-conne
