H(2)O () are obtained. Compounds have a layer structure in which the chiral inorganic double chains, made up of corner-sharing ZnO(4)} and PO(3)C} tetrahedra, are connected by bdc(2-). While in compounds , chiral chains of zinc phosphonate are each connected to their four equivalent neighbors through btec(4-) linkages, resulting in an open framework structure. All these compounds are optically active
