Materials Data on CeMo12(NO27)2 by Materials Project
Ce(Mo2O7)6N2(O2)6 crystallizes in the trigonal R-3 space group. The structure is zero-dimensional and consists of six ammonia molecules, eighteen water water molecules, and three Ce(Mo2O7)6 clusters. In each Ce(Mo2O7)6 cluster, Ce is bonded in a cuboctahedral geometry to twelve O atoms. There are six shorter (2.50 Å) and six longer (2.57 Å) Ce–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 1.72–2.31 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 1.73–2.40 Å. There are seven inequivalent O sites. In the first O site, O is bonded in a water-like geometry to two Mo atoms. 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 distorted rectangular see-saw-like geometry to one Ce and three Mo atoms. In the sixth O site, O is bonded in a single-bond geometry to one Mo atom. In the seventh O site, O is bonded in a distorted rectangular see-saw-like geometry to one Ce and three Mo atoms.
