Tc Sb Os Os Os
TcOs3Sb is Pb (Zr_0.50 Ti_0.48) O_3 structured and crystallizes in the trigonal R3m space group. Tc(1) is bonded in a 9-coordinate geometry to nine equivalent Os(1) atoms. There are three shorter (2.58 Å) and six longer (3.46 Å) Tc(1)-Os(1) bond lengths. Os(1) is bonded in a 1-coordinate geometry to three equivalent Tc(1) and one Sb(1) atom. The Os(1)-Sb(1) bond length is 1.82 Å. Sb(1) is bonded in a distorted octahedral geometry to three equivalent Os(1) atoms.
