Materials Data on OsC3IO3 by Materials Project
IOs(CO)3 crystallizes in the monoclinic P2_1/m space group. The structure is zero-dimensional and consists of twelve formaldehyde molecules and two IOs clusters. In each IOs cluster, Os3+ is bonded in a 2-coordinate geometry to two I1- atoms. There are one shorter (2.78 Å) and one longer (2.80 Å) Os–I bond lengths. There are two inequivalent I1- sites. In the first I1- site, I1- is bonded in a 6-coordinate geometry to two equivalent Os3+ atoms. In the second I1- site, I1- is bonded in a 4-coordinate geometry to two equivalent Os3+ atoms.
