Tc As Os Os
TcOs2As crystallizes in the monoclinic Cm space group. Tc(1) is bonded in a distorted body-centered cubic geometry to four equivalent Os(1), four equivalent Os(2), and one As(1) atom. There are a spread of Tc(1)-Os(1) bond distances ranging from 2.20-2.57 Å. There are a spread of Tc(1)-Os(2) bond distances ranging from 2.20-2.57 Å. The Tc(1)-As(1) bond length is 3.10 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 4-coordinate geometry to four equivalent Tc(1) and three equivalent As(1) atoms. There is one shorter (3.17 Å) and two longer (3.30 Å) Os(1)-As(1) bond lengths. In the second Os site, Os(2) is bonded in a 4-coordinate geometry to four equivalent Tc(1) and four equivalent As(1) atoms. There are a spread of Os(2)-As(1) bond distances ranging from 2.63-2.95 Å. As(1) is bonded in a 12-coordinate geometry to one Tc(1), three equivalent Os(1), four equivalent Os(2), and four equivalent As(1) atoms. All As(1)-As(1) bond lengths are 2.90 Å.
