Ti Be Pt Pt
BeTiPt2 crystallizes in the triclinic P1 space group. Be(1) is bonded in a 5-coordinate geometry to one Ti(1), two equivalent Pt(1), and two equivalent Pt(2) atoms. The Be(1)-Ti(1) bond length is 0.83 Å. There is one shorter (2.61 Å) and one longer (2.85 Å) Be(1)-Pt(1) bond length. There is one shorter (2.26 Å) and one longer (2.53 Å) Be(1)-Pt(2) bond length. Ti(1) is bonded in a 5-coordinate geometry to one Be(1), two equivalent Pt(1), and two equivalent Pt(2) atoms. There is one shorter (2.26 Å) and one longer (2.53 Å) Ti(1)-Pt(1) bond length. There is one shorter (2.61 Å) and one longer (2.85 Å) Ti(1)-Pt(2) bond length. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 6-coordinate geometry to two equivalent Be(1), two equivalent Ti(1), and two equivalent Pt(2) atoms. There is one shorter (2.16 Å) and one longer (2.35 Å) Pt(1)-Pt(2) bond length. In the second Pt site, Pt(2) is bonded in a 6-coordinate geometry to two equivalent Be(1), two equivalent Ti(1), and two equivalent Pt(1) atoms.
