The crystal structure described by Tc(CO)5 is Cubic alpha N2-like structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of eight Tc(CO)5 clusters. Tc(1) is bonded in a square pyramidal geometry to one C(1), one C(2), one C(3), one C(4), and one C(5) atom. There are five inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one Tc(1) and one O(1) atom. In the second C site, C(2) is bonded in a linear geometry to one Tc(1) and one O(2) atom. In the third C site, C(3) is bonded in a linear geometry to one Tc(1) and one O(5) atom. In the fourth C site, C(4) is bonded in a linear geometry to one Tc(1) and one O(4) atom. In the fifth C site, C(5) is bonded in a linear geometry to one Tc(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(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one C(2) 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(4) is bonded in a single-bond geometry to one C(4) atom. In the fifth O site, O(5) is bonded in a single-bond geometry to one C(3) atom. is represented by the CIF file [CIF]
