Cr Pd Pd Pb
CrPd2Pb crystallizes in the monoclinic Cm space group. Cr(1) is bonded in a single-bond geometry to four equivalent Pd(1) and one Pb(1) atom. There are a spread of Cr(1)-Pd(1) bond distances ranging from 3.26-3.36 Å. The Cr(1)-Pb(1) bond length is 0.23 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to four equivalent Cr(1), one Pd(2), and four equivalent Pd(1) atoms. The Pd(1)-Pd(2) bond length is 2.36 Å. All Pd(1)-Pd(1) bond lengths are 2.96 Å. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to one Pd(1), four equivalent Pd(2), and four equivalent Pb(1) atoms. All Pd(2)-Pd(2) bond lengths are 2.96 Å. There are a spread of Pd(2)-Pb(1) bond distances ranging from 3.44-3.54 Å. Pb(1) is bonded in a single-bond geometry to one Cr(1) and four equivalent Pd(2) atoms.
