title: Materials Data on H5IO6 by Materials Project

description: H5IO6 crystallizes in the monoclinic P2_1 space group. The structure is two-dimensional and consists of two H5IO6 sheets oriented in the (0, 1, 0) direction. there are ten inequivalent H sites. In the first H site, H is bonded in a linear geometry to two O atoms. There is one shorter (1.08 Å) and one longer (1.42 Å) H–O bond length. In the second H site, H is bonded in a distorted linear geometry to two O atoms. There is one shorter (1.04 Å) and one longer (1.60 Å) H–O bond length. In the third H site, H is bonded in a linear geometry to two O atoms. There is one shorter (1.08 Å) and one longer (1.40 Å) H–O bond length. In the fourth H site, H is bonded in a single-bond geometry to one O atom. The H–O bond length is 0.99 Å. In the fifth H site, H is bonded in a single-bond geometry to one O atom. The H–O bond length is 1.01 Å. In the sixth H site, H is bonded in a single-bond geometry to one O atom. The H–O bond length is 1.00 Å. In the seventh H site, H is bonded in a linear geometry to two O atoms. There is one shorter (1.01 Å) and one longer (1.62 Å) H–O bond length. In the eighth H site, H is bonded in a linear geometry to two O atoms. There is one shorter (1.03 Å) and one longer (1.58 Å) H–O bond length. In the ninth H site, H is bonded in a single-bond geometry to one O atom. The H–O bond length is 1.00 Å. In the tenth H site, H is bonded in a single-bond geometry to one O atom. The H–O bond length is 1.00 Å. There are twelve inequivalent O sites. In the first O site, O is bonded in a distorted bent 120 degrees geometry to one H and one I atom. The O–I bond length is 1.88 Å. In the second O site, O is bonded in a distorted trigonal planar geometry to two H and one I atom. The O–I bond length is 1.99 Å. In the third O site, O is bonded in a distorted trigonal planar geometry to two H and one I atom. The O–I bond length is 1.90 Å. In the fourth O site, O is bonded in a trigonal planar geometry to two H and one I atom. The O–I bond length is 1.86 Å. In the fifth O site, O is bonded in a distorted single-bond geometry to one H and one I atom. The O–I bond length is 1.92 Å. In the sixth O site, O is bonded in a bent 120 degrees geometry to one H and one I atom. The O–I bond length is 1.82 Å. In the seventh O site, O is bonded in a distorted single-bond geometry to one H and one I atom. The O–I bond length is 1.94 Å. In the eighth O site, O is bonded in a distorted single-bond geometry to one H and one I atom. The O–I bond length is 1.95 Å. In the ninth O site, O is bonded in a distorted water-like geometry to one H and one I atom. The O–I bond length is 1.89 Å. In the tenth O site, O is bonded in a distorted single-bond geometry to one H and one I atom. The O–I bond length is 1.92 Å. In the eleventh O site, O is bonded in a distorted single-bond geometry to one H and one I atom. The O–I bond length is 1.93 Å. In the twelfth O site, O is bonded in a distorted single-bond geometry to one H and one I atom. The O–I bond length is 1.97 Å. There are two inequivalent I sites. In the first I site, I is bonded in an octahedral geometry to six O atoms. In the second I site, I is bonded in an octahedral geometry to six O atoms.
