description: MgZn2P2(H6O5)4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Mg2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Mg–O bond distances ranging from 2.04–2.13 Å. Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with three equivalent PO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.95–2.02 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent ZnO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.55–1.58 Å. There are twelve inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the sixth H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.56 Å) H–O bond length. In the seventh H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.65 Å) H–O bond length.
