Hg Mo Pt
MoPtHg crystallizes in the triclinic P1 space group. Mo(1) is bonded in a 4-coordinate geometry to two equivalent Pt(1) and two equivalent Hg(1) atoms. There is one shorter (1.86 Å) and one longer (2.29 Å) Mo(1)-Pt(1) bond length. There is one shorter (1.83 Å) and one longer (2.26 Å) Mo(1)-Hg(1) bond length. Pt(1) is bonded in a 4-coordinate geometry to two equivalent Mo(1) and two equivalent Hg(1) atoms. There is one shorter (2.65 Å) and one longer (2.73 Å) Pt(1)-Hg(1) bond length. Hg(1) is bonded in a 4-coordinate geometry to two equivalent Mo(1) and two equivalent Pt(1) atoms.
