Abstract

RuC(RuC2O2I)2(CO)5 crystallizes in the orthorhombic Pna2_1 space group. The structure is two-dimensional and consists of twenty formaldehyde molecules; four RuC clusters; and two RuC2O2I sheets oriented in the (0, 0, 1) direction. In each RuC cluster, Ru4+ is bonded in a distorted single-bond geometry to one C+0.80+ atom. The Ru–C bond length is 1.77 Å. C+0.80+ is bonded in a single-bond geometry to one Ru4+ atom. In each RuC2O2I sheet, there are two inequivalent Ru4+ sites. In the first Ru4+ site, Ru4+ is bonded in a 5-coordinate geometry to two I1- atoms. There are one shorter (2.80 Å) and one longer (2.82 Å) Ru–I bond lengths. In the second Ru4+ site, Ru4+ is bonded in a 2-coordinate geometry to two I1- atoms. There are one shorter (2.81 Å) and one longer (2.83 Å) Ru–I bond lengths. There are four inequivalent C+0.80+ sites. In the first C+0.80+ site, C+0.80+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.16 Å. In the second C+0.80+ site, C+0.80+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.16 Å. In the third C+0.80+ site, C+0.80+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.16 Å. In the fourth C+0.80+ site, C+0.80+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.15 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one C+0.80+ and one I1- atom. The O–I bond length is 3.82 Å. In the second O2- site, O2- is bonded in a single-bond geometry to one C+0.80+ and one I1- atom. The O–I bond length is 3.61 Å. In the third O2- site, O2- is bonded in a single-bond geometry to one C+0.80+ and two I1- atoms. There are one shorter (3.57 Å) and one longer (3.89 Å) O–I bond lengths. In the fourth O2- site, O2- is bonded in a single-bond geometry to one C+0.80+ and three I1- atoms. There are a spread of O–I bond distances ranging from 3.74–3.90 Å. There are two inequivalent I1- sites. In the first I1- site, I1- is bonded in a 6-coordinate geometry to two Ru4+ and four O2- atoms. In the second I1- site, I1- is bonded in a 5-coordinate geometry to two Ru4+ and three O2- atoms.
