Materials Data on U(MoO5)12 by Materials Project
U(MoO4)12(O2)6 crystallizes in the trigonal R-3 space group. The structure is zero-dimensional and consists of three hexaoxane molecules, six trioxirane molecules, and three U(MoO4)12 clusters. In each U(MoO4)12 cluster, U is bonded in a cuboctahedral geometry to twelve O atoms. There are six shorter (2.40 Å) and six longer (2.51 Å) U–O bond lengths. 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 1.72–2.32 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 1.73–2.35 Å. There are eight inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Mo atom. In the second O site, O is bonded in a single-bond geometry to one Mo atom. In the third O site, O is bonded in a single-bond geometry to one Mo atom. In the fourth O site, O is bonded in a single-bond geometry to one Mo atom. In the fifth O site, O is bonded in a single-bond geometry to one O atom. The O–O bond length is 2.04 Å. In the sixth O site, O is bonded in a distorted rectangular see-saw-like geometry to one U and three Mo atoms. In the seventh O site, O is bonded in a water-like geometry to two Mo and one O atom. In the eighth O site, O is bonded in a distorted rectangular see-saw-like geometry to one U and three Mo atoms.
