Co3Bi(CO)9 is Indium-like structured and crystallizes in the hexagonal P6_3mc space group. The structure is zero-dimensional and consists of two Co3Bi(CO)9 clusters. Co(1) is bonded to one C(2), one C(3), two equivalent C(1), and one Bi(1) atom to form distorted edge-sharing CoBiC4 trigonal pyramids. There are three inequivalent C sites. In the first C site, C(1) is bonded in a 3-coordinate geometry to two equivalent Co(1) and one O(2) atom. In the second C site, C(2) is bonded in a linear geometry to one Co(1) and one O(1) atom. In the third C site, C(3) is bonded in a linear geometry to one Co(1) and one O(3) atom. Bi(1) is bonded in a 3-coordinate geometry to three equivalent Co(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one C(2) atom. In the second O site, O(2) is bonded in a single-bond geometry to one C(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one C(3) atom.
