Two new zincophosphates, bis(ethylenediammonim) catena-bis({mu}-phosphato)zincate, (H{sub 3}NCH{sub 2}CH{sub 2}NH{sub 3}){sub 2}[Zn({mu}-PO{sub 4}){sub 2}] (1), and ammonium ammine-tris({mu}-phosphato)tetrazincate, (NH{sub 4})[(H{sub 3}N)Zn{l_brace}({mu}-PO{sub 4})Zn{r_brace}{sub 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 ZnP{sub 2}O{sub 8}{sup 4-} chains, running along the [0 0 1] direction, and diprotonated ethylenediammonium cations, H{sub 2}en{sup 2+}. The crystal structure of 2 is built up from ZnO{sub 4}, Zn(NH{sub 3})O{sub 3} and PO{sub 4} vertex-sharing tetrahedra connected to form an open 3D framework. The ammonium groups, NH{sub 4}{sup +}, are located in the channels formed by 8M-rings extending along [1 0 0]. In order to study vibrational behavior of H{sub 2}en{sup 2+} and NH{sub 4}{sup +} cations, NH{sub 3} 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. - Graphical Abstract: Structure of 1 (left): polyhedral (a) and ORTEP-like (b) representation of the ZnP{sub 2}O{sub 8}{sup 4-} chain with two H{sub 2}en{sup 2+} cations. Structure of 2 (right): polyhedral structure of the layers I and II seen along [1 0 0] (c-axis is vertical). Highlights: > Synthesis under hydrothermal conditions and the crystal structures of two new zincophosphates. > Compound 1 is a new inorganic-organic hybrid compound. > Structure of 1 consists of infinite macroanionic ZnP{sub 2}O{sub 8}{sup 4-} chains and H{sub 2}en{sup 2+} (en=ethylenediamine) cations. > Structure of 2 is a novel 3D open framework structure with 8M channels. > Structure of 2 is the first 3D zincophosphate which incorporates both, the coordinated NH{sub 3} molecule and NH{sub 4}{sup +} cations.
