Materials Data on Sr(ClO3)2 by Materials Project

Sr(O3Cl)2 crystallizes in the monoclinic C2 space group. The structure is one-dimensional and consists of two Sr(O3Cl)2 ribbons oriented in the (0, 0, 1) direction. Sr is bonded in a 7-coordinate geometry to seven O atoms. There are a spread of Sr–O bond distances ranging from 2.46–2.57 Å. There are four inequivalent O sites. In the first O site, O is bonded in a bent 120 degrees geometry to one O and one Cl atom. The O–O bond length is 1.34 Å. The O–Cl bond length is 1.81 Å. In the second O site, O is bonded in a 3-coordinate geometry to one Sr and two equivalent O atoms. Both O–O bond lengths are 1.80 Å. In the third O site, O is bonded in a distorted T-shaped geometry to two equivalent Sr and one O atom. In the fourth O site, O is bonded in a 4-coordinate geometry to two equivalent Sr and two equivalent O atoms. Cl is bonded in a single-bond geometry to one O atom.
