Materials Data on Re3Se4O9 by Materials Project
Re3Se4O3(O2)3 crystallizes in the trigonal R-3m space group. The structure is zero-dimensional and consists of eighteen hydrogen peroxide molecules and three Re3Se4O3 clusters. In each Re3Se4O3 cluster, Re+6.67+ is bonded in a distorted single-bond geometry to four Se+0.50- and one O2- atom. There are a spread of Re–Se bond distances ranging from 2.52–2.54 Å. The Re–O bond length is 1.70 Å. There are two inequivalent Se+0.50- sites. In the first Se+0.50- site, Se+0.50- is bonded in a 3-coordinate geometry to three equivalent Re+6.67+ atoms. In the second Se+0.50- site, Se+0.50- is bonded in a 3-coordinate geometry to three equivalent Re+6.67+ atoms. O2- is bonded in a single-bond geometry to one Re+6.67+ atom.
