ReH(CO)4 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two ReH(CO)4 clusters. there are three inequivalent Re7+ sites. In the first Re7+ site, Re7+ is bonded to four C and two H1+ atoms to form corner-sharing ReH2C4 octahedra. The corner-sharing octahedra tilt angles range from 49–50°. There is two shorter (1.94 Å) and two longer (2.00 Å) Re–C bond length. There is one shorter (1.87 Å) and one longer (1.89 Å) Re–H bond length. In the second Re7+ site, Re7+ is bonded to four C and two H1+ atoms to form corner-sharing ReH2C4 octahedra. The corner-sharing octahedral tilt angles are 50°. There are a spread of Re–C bond distances ranging from 1.94–2.01 Å. There is one shorter (1.88 Å) and one longer (1.89 Å) Re–H bond length. In the third Re7+ site, Re7+ is bonded to four C and two H1+ atoms to form corner-sharing ReH2C4 octahedra. The corner-sharing octahedra tilt angles range from 49–50°.
