Materials Data on W2C7Br4O7 by Materials Project
(WBr2)2(CO)7 crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of twenty-eight formaldehyde molecules and four WBr2 clusters. In each WBr2 cluster, there are two inequivalent W6+ sites. In the first W6+ site, W6+ is bonded in a 3-coordinate geometry to three Br1- atoms. There are two shorter (2.71 Å) and one longer (2.74 Å) W–Br bond lengths. In the second W6+ site, W6+ is bonded in a distorted rectangular see-saw-like geometry to four Br1- atoms. There are a spread of W–Br bond distances ranging from 2.69–2.78 Å. There are three inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a 2-coordinate geometry to two W6+ atoms. In the second Br1- site, Br1- is bonded in a distorted L-shaped geometry to two W6+ atoms. In the third Br1- site, Br1- is bonded in a single-bond geometry to one W6+ atom.
