Materials Data on Re(Cl2O)2 by Materials Project

Abstract

Re(OCl2)2 crystallizes in the orthorhombic Pna2_1 space group. The structure is zero-dimensional and consists of four Re(OCl2)2 clusters. Re is bonded in a 6-coordinate geometry to two O and four Cl atoms. There is one shorter (1.74 Å) and one longer (1.83 Å) Re–O bond length. There are a spread of Re–Cl bond distances ranging from 2.24–2.54 Å. There are two inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Re and one Cl atom. The O–Cl bond length is 2.33 Å. In the second O site, O is bonded in a single-bond geometry to one Re atom. There are four inequivalent Cl sites. In the first Cl site, Cl is bonded in a 1-coordinate geometry to one Re and one O atom. In the second Cl site, Cl is bonded in a single-bond geometry to one Re atom. In the third Cl site, Cl is bonded in a single-bond geometry to one Re atom. In the fourth Cl site, Cl is bonded in a single-bond geometry to one Re atom.
