The crystal structure described by CoAg(CO)4 is Indium-like structured and crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of two CoAg(CO)4 clusters. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent Ag(1), two equivalent C(2), and two equivalent C(5) atoms to form distorted corner-sharing CoAg2C4 tetrahedra. In the second Co site, Co(2) is bonded to two equivalent Ag(1), one C(1), one C(3), and two equivalent C(4) atoms to form distorted corner-sharing CoAg2C4 tetrahedra. Ag(1) is bonded in a 8-coordinate geometry to one Co(1), one Co(2), two equivalent Ag(1), one C(1), one C(3), and two equivalent C(2) atoms. There are five inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one Co(2), two equivalent Ag(1), and one O(5) atom. In the second C site, C(2) is bonded in a distorted linear geometry to one Co(1), two equivalent Ag(1), and one O(1) atom. In the third C site, C(3) is bonded in a distorted linear geometry to one Co(2), two equivalent Ag(1), and one O(2) atom. In the fourth C site, C(4) is bonded in a linear geometry to one Co(2) and one O(4) atom. In the fifth C site, C(5) is bonded in a linear geometry to one Co(1) and one O(3) atom. There are five 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(3) atom. In the third O site, O(3) is bonded in a single-bond geometry to one C(5) atom. In the fourth O site, O(5) is bonded in a single-bond geometry to one C(1) atom. In the fifth O site, O(4) is bonded in a single-bond geometry to one C(4) atom. is represented by the CIF file [CIF]
