La Tc Pt Pt
LaTcPt2 crystallizes in the triclinic P1 space group. La(1) is bonded in a 2-coordinate geometry to one Tc(1), one Pt(1), and three equivalent Pt(2) atoms. The La(1)-Tc(1) bond length is 1.97 Å. The La(1)-Pt(1) bond length is 2.56 Å. There are a spread of La(1)-Pt(2) bond distances ranging from 2.99-3.72 Å. Tc(1) is bonded in a distorted bent 120 degrees geometry to one La(1), one Pt(1), and one Pt(2) atom. The Tc(1)-Pt(1) bond length is 0.96 Å. The Tc(1)-Pt(2) bond length is 2.46 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted single-bond geometry to one La(1), one Tc(1), and two equivalent Pt(2) atoms. There is one shorter (2.38 Å) and one longer (3.19 Å) Pt(1)-Pt(2) bond length. In the second Pt site, Pt(2) is bonded in a 8-coordinate geometry to three equivalent La(1), one Tc(1), two equivalent Pt(1), and two equivalent Pt(2) atoms. Both Pt(2)-Pt(2) bond lengths are 3.04 Å.
