Materials Data on CuMo3O11 by Materials Project
(Mo3CuO10)2O2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional and consists of four water molecules and one Mo3CuO10 framework. In the Mo3CuO10 framework, there are two inequivalent Mo sites. In the first Mo site, Mo is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Mo–O bond distances ranging from 1.78–2.23 Å. In the second Mo site, Mo is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Mo–O bond distances ranging from 1.72–2.30 Å. Cu is bonded in a distorted trigonal pyramidal geometry to four O atoms. There is two shorter (1.87 Å) and two longer (2.01 Å) Cu–O bond length. There are seven inequivalent O sites. In the first O site, O is bonded in a bent 150 degrees geometry to one Mo and one Cu atom. In the second O site, O is bonded in a bent 120 degrees geometry to one Mo and one Cu atom. In the third O site, O is bonded in a bent 150 degrees geometry to one Mo and one Cu atom. In the fourth O site, O is bonded in a distorted T-shaped geometry to three Mo atoms. In the fifth O site, O is bonded in a single-bond geometry to one Mo atom. In the sixth O site, O is bonded in a 3-coordinate geometry to three Mo atoms. In the seventh O site, O is bonded in a trigonal non-coplanar geometry to three Mo atoms.
