Title: Materials Data on Ni(IO3)2 by Materials Project

Abstract

Ni(IO3)2 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is two-dimensional and consists of two Ni(IO3)2 sheets oriented in the (0, 0, 1) direction. Ni2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ni–O bond distances ranging from 2.06–2.52 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Ni2+ and three I5+ atoms. There are a spread of O–I bond distances ranging from 1.89–2.73 Å. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ni2+ and one I5+ atom. The O–I bond length is 1.86 Å. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Ni2+ and two equivalent I5+ atoms. There are one shorter (1.86 Å) and one longer (2.67 Å) O–I bond lengths. In the fourth O2- site, O2- is bonded in a water-like geometry to one Ni2+ and one I5+ atom. The O–I bond length is 1.84 Å. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one Ni2+ and one I5+ atom. The O–I bond length is 1.86more » Å. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ni2+ and one I5+ atom. The O–I bond length is 1.88 Å. There are two inequivalent I5+ sites. In the first I5+ site, I5+ is bonded in a 6-coordinate geometry to three O2- atoms. In the second I5+ site, I5+ is bonded to six O2- atoms to form distorted corner-sharing IO6 octahedra. The corner-sharing octahedra tilt angles range from 44–70°.« less
