Os Pt Pt Pb
OsPt2Pb is Protactinium-derived structured and crystallizes in the tetragonal P4mm space group. Os(1) is bonded in a 10-coordinate geometry to two equivalent Os(1) and eight equivalent Pt(1) atoms. Both Os(1)-Os(1) bond lengths are 2.82 Å. There are four shorter (2.76 Å) and four longer (3.00 Å) Os(1)-Pt(1) bond lengths. Pt(1) is bonded in a 10-coordinate geometry to four equivalent Os(1), two equivalent Pt(1), and four equivalent Pb(1) atoms. Both Pt(1)-Pt(1) bond lengths are 2.82 Å. There are two shorter (2.76 Å) and two longer (3.00 Å) Pt(1)-Pb(1) bond lengths. Pb(1) is bonded in a 10-coordinate geometry to eight equivalent Pt(1) and two equivalent Pb(1) atoms. Both Pb(1)-Pb(1) bond lengths are 2.82 Å.
