Crystal structure of a new homochiral one-dimensional zincophosphate containing l-methionine
Abstract
catena-Poly[[(l-methionine-κO)zinc]-μ3-(hydrogen phosphato)-κ3O:O′:O′′], [Zn{PO3(OH)}(C5H11NO2S)]n, a new one-dimensional homochiral zincophosphate, was hydrothermally synthesized using l-methionine as a structure-directing agent. The compound consists of a network of ZnO4 and (HO)PO3 tetrahedra that form ladder-like chains of edge-fused Zn2P2O4 rings propagating parallel to [100]. The chains are decorated on each side by zwitterionic l-methionine ligands, which interact with the inorganic framework via Zn—O coordination bonds. The structure displays interchain N—H...O and O—H...S hydrogen bonds.
