description: BaZn2(H7O5)2H2O crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of four water molecules and one BaZn2(H7O5)2 sheet oriented in the (0, 0, 1) direction. In the BaZn2(H7O5)2 sheet, Ba2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.73–3.17 Å. There are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to four O2- atoms to form corner-sharing ZnO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.96–2.02 Å. In the second Zn2+ site, Zn2+ is bonded to four O2- atoms to form corner-sharing ZnO4 tetrahedra. There is one shorter (1.96 Å) and three longer (2.00 Å) Zn–O bond length. There are fourteen 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 0.98 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 0.98 Å. In the fourth 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 fifth 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 sixth 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 seventh H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.60 Å) H–O bond length. In the eighth 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 ninth 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 tenth H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2- atom. The H–O bond length is 1.02 Å. In the eleventh 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 twelfth 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 thirteenth 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 fourteenth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Zn2+ and one H1+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Zn2+ and one H1+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+, one Zn2+, and one H1+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+, two equivalent Zn2+, and one H1+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Zn2+ and one H1+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+, one Zn2+, and two H1+ atoms. In the seventh O2- site, O2- is bonded in a water-like geometry to two equivalent Ba2+ and two H1+ atoms. In the eighth O2- site, O2- is bonded in a water-like geometry to two equivalent Ba2+ and two H1+ atoms. In the ninth O2- site, O2- is bonded in a water-like geometry to one Ba2+ and two H1+ atoms. In the tenth O2- site, O2- is bonded in a water-like geometry to one Ba2+ and two H1+ atoms.
