The structure described by Ru(CO)4 crystallizes in the orthorhombic Iba2 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 linear geometry to one Ru(1) and one O(1) atom. In the second C site, C(2) is bonded in a distorted linear geometry to one Ru(1) and one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one C(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one C(2) atom. is represented by the CIF file [CIF]
