Materials Data on RhSe2Cl7 by Materials Project
RhSeCl5SeCl2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four selenium dichloride molecules and two RhSeCl5 clusters. In each RhSeCl5 cluster, Rh3+ is bonded in a rectangular see-saw-like geometry to four Cl1- atoms. There are a spread of Rh–Cl bond distances ranging from 2.36–2.46 Å. Se2+ is bonded in a 4-coordinate geometry to four Cl1- atoms. There are a spread of Se–Cl bond distances ranging from 2.19–2.87 Å. There are five inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Rh3+ and one Se2+ atom. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one Se2+ atom. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Se2+ atom. In the fourth Cl1- site, Cl1- is bonded in a water-like geometry to two equivalent Rh3+ atoms. In the fifth Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Rh3+ and one Se2+ atom.
