Materials Data on VSb(SeO3)4 by Materials Project
VSb(SeO3)4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. V5+ is bonded in an octahedral geometry to six O2- atoms. There are four shorter (2.03 Å) and two longer (2.06 Å) V–O bond lengths. Sb5+ is bonded in an octahedral geometry to six O2- atoms. There are two shorter (2.00 Å) and four longer (2.03 Å) Sb–O bond lengths. There are two inequivalent Se+3.50+ sites. In the first Se+3.50+ site, Se+3.50+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.70 Å) and one longer (1.82 Å) Se–O bond length. In the second Se+3.50+ site, Se+3.50+ is bonded in a distorted T-shaped geometry to three O2- atoms. There is one shorter (1.69 Å) and two longer (1.78 Å) Se–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one V5+ and one Se+3.50+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Sb5+ and one Se+3.50+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Sb5+ and one Se+3.50+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one V5+ and one Se+3.50+ atom. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one Sb5+ and one Se+3.50+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one V5+ and one Se+3.50+ atom.
