Materials Data on ReNCl4O3 by Materials Project
ReNO3Cl4 is alpha Np structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of eight ReNO3Cl4 clusters. In four of the ReNO3Cl4 clusters, Re5+ is bonded in a 2-coordinate geometry to two O2- and four Cl1- atoms. There is one shorter (1.71 Å) and one longer (1.73 Å) Re–O bond length. There are a spread of Re–Cl bond distances ranging from 2.29–2.93 Å. N5+ is bonded in a distorted single-bond geometry to one O2- and one Cl1- atom. The N–O bond length is 1.13 Å. The N–Cl bond length is 2.34 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Re5+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one N5+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Re5+ atom. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 2-coordinate geometry to one Re5+ and one N5+ atom. In the second Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Re5+ atom. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Re5+ atom. In the fourth Cl1- site, Cl1- is bonded in a single-bond geometry to one Re5+ atom. In four of the ReNO3Cl4 clusters, Re5+ is bonded in a 2-coordinate geometry to two O2- and four Cl1- atoms. Both Re–O bond lengths are 1.72 Å. There are a spread of Re–Cl bond distances ranging from 2.30–2.61 Å. N5+ is bonded in a single-bond geometry to one O2- and one Cl1- atom. The N–O bond length is 1.13 Å. The N–Cl bond length is 2.49 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Re5+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one N5+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Re5+ atom. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one Re5+ atom. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one Re5+ atom. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Re5+ atom. In the fourth Cl1- site, Cl1- is bonded in a 2-coordinate geometry to one Re5+ and one N5+ atom.
