Materials Data on TcOs3 by Materials Project
TcOs3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Tc3- is bonded to twelve equivalent Os1+ atoms to form a mixture of face and corner-sharing TcOs12 cuboctahedra. There are six shorter (2.70 Å) and six longer (2.76 Å) Tc–Os bond lengths. Os1+ is bonded in a see-saw-like geometry to four equivalent Tc3- atoms.
