NaCo(CO)4 crystallizes in the orthorhombic Pbcm space group. Na(1) is bonded in a 4-coordinate geometry to one O(1), one O(2), and two equivalent O(3) atoms. Co(1) is bonded in a tetrahedral geometry to one C(2), one C(3), and two equivalent C(1) atoms. There are three inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one Co(1) and one O(3) 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 distorted linear geometry to one Co(1) and one O(2) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one Na(1) and one C(2) atom. In the second O site, O(2) is bonded in a distorted linear geometry to one Na(1) and one C(3) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Na(1) and one C(1) atom.
