Tc Tc B Pt
Tc2PtB crystallizes in the triclinic P1 space group. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 2-coordinate geometry to one Tc(2), one Pt(1), and one B(1) atom. The Tc(1)-Tc(2) bond length is 1.63 Å. The Tc(1)-Pt(1) bond length is 1.44 Å. The Tc(1)-B(1) bond length is 0.59 Å. In the second Tc site, Tc(2) is bonded in a 8-coordinate geometry to one Tc(1), two equivalent Tc(2), three equivalent Pt(1), and two equivalent B(1) atoms. Both Tc(2)-Tc(2) bond lengths are 2.82 Å. There are a spread of Tc(2)-Pt(1) bond distances ranging from 2.45-2.68 Å. There is one shorter (1.61 Å) and one longer (2.88 Å) Tc(2)-B(1) bond length. Pt(1) is bonded in a distorted single-bond geometry to one Tc(1) and three equivalent Tc(2) atoms. B(1) is bonded in a single-bond geometry to one Tc(1) and two equivalent Tc(2) atoms.
