Ru(CO)4 crystallizes in the orthorhombic Ibam space group. The structure is zero-dimensional and consists of four Ru(CO)4 clusters. Ru(1) is bonded in a square co-planar geometry to two equivalent C(1) and two equivalent C(2) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted linear geometry to one Ru(1) and one O(1,2) atom. In the second C site, C(2) is bonded in a distorted linear geometry to one Ru(1) and one O(1,2) atom. O(1,2) is bonded in a single-bond geometry to one C(1) atom.
Ru(CO)4 crystallizes in the orthorhombic Ibam space group. The structure is zero-dimensional and consists of four Ru(CO)4 clusters. Ru(1) is bonded in a square co-planar geometry to two equivalent C(1) and two equivalent C(2) atoms. Both Ru(1)-C(1) bond lengths are 1.95 Å. Both Ru(1)-C(2) bond lengths are 1.95 Å. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted linear geometry to one Ru(1) and one O(1,2) atom. The C(1)-O(1,2) bond length is 1.16 Å. In the second C site, C(2) is bonded in a distorted linear geometry to one Ru(1) and one O(1,2) atom. The C(2)-O(1,2) bond length is 1.16 Å. O(1,2) is bonded in a single-bond geometry to one C(1) atom.
