Two new zincophosphates, bis(ethylenediammonim) catena-bis(µ-phosphato)zincate, (H3NCH2CH2NH3)2[Zn(µ-PO4)2] (1), and ammonium ammine-tris(µ-phosphato)tetrazincate, (NH4)[(H3N)Zn{(µ-PO4)Zn}3] (2), were synthesized under hydrothermal conditions and their crystal structures were determined by single-crystal X-ray diffraction analysis. The crystal structure of 1 consists of infinite macroanionic ZnP2O84- chains, running along the [0 0 1] direction, and diprotonated ethylenediammonium cations, H2en2+. The crystal structure of 2 is built up from ZnO4, Zn(NH3)O3 and PO4 vertex-sharing tetrahedra connected to form an open 3D framework. The ammonium groups, NH4+, are located in the channels formed by 8M-rings extending along [1 0 0]. In order to study vibrational behavior of H2en2+ and NH4+ cations, NH3 molecules in 1 and 2, single-crystal Raman spectra were obtained. Structural, chemical and topological similarities to the other open framework zinco- and aluminophosphates incorporating different guest species are discussed.
