Materials Data on SiW12C16(NO10)4 by Materials Project

(W3CO10)4Si(C)4(C2N)4 crystallizes in the tetragonal I-4 space group. The structure is zero-dimensional and consists of eight ch3nc molecules, eight methane molecules, two silicon molecules, and two W3CO10 clusters. In each W3CO10 cluster, there are three inequivalent W6+ sites. In the first W6+ site, W6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of W–O bond distances ranging from 1.74–2.43 Å. In the second W6+ site, W6+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of W–O bond distances ranging from 1.83–2.21 Å. In the third W6+ site, W6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of W–O bond distances ranging from 1.73–2.42 Å. C1+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.25 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a water-like geometry to two W6+ atoms. In the second O2- site, O2- is bonded in a single-bond geometry to one W6+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to three W6+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one W6+ and one C1+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one W6+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to two W6+ atoms. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to two W6+ atoms. In the eighth O2- site, O2- is bonded in a water-like geometry to two W6+ atoms. In the ninth O2- site, O2- is bonded in a bent 150 degrees geometry to two W6+ atoms. In the tenth O2- site, O2- is bonded in a bent 120 degrees geometry to two W6+ atoms.
