Crystal structure of a new homochiral one-dimensional zincophosphate containing l-me-thio-nine.

catena-Poly[[(l-me-thio-nine-κO)zinc]-µ3-(hydrogen phosphato)-κ(3) O:O':O''], [Zn{PO3(OH)}(C5H11NO2S)] n , a new one-dimensional homochiral zincophos-phate, was hydro-thermally synthesized using l-me-thio-nine as a structure-directing agent. The compound consists of a network of ZnO4 and (HO)PO3 tetra-hedra that form ladder-like chains of edge-fused Zn2P2O4 rings propagating parallel to [100]. The chains are decorated on each side by zwitterionic l-me-thio-nine ligands, which inter-act with the inorganic framework via Zn-O coordination bonds. The structure displays inter-chain N-H⋯O and O-H⋯S hydrogen bonds.
