Zn Cr Rh Pb
CrRhZnPb crystallizes in the trigonal R3m space group. Cr(1) is bonded in a distorted single-bond geometry to three equivalent Rh(1), one Zn(1), and four equivalent Pb(1) atoms. All Cr(1)-Rh(1) bond lengths are 2.69 Å. The Cr(1)-Zn(1) bond length is 1.14 Å. There are three shorter (2.77 Å) and one longer (3.01 Å) Cr(1)-Pb(1) bond length. Rh(1) is bonded in a distorted q6 geometry to three equivalent Cr(1), four equivalent Zn(1), and three equivalent Pb(1) atoms. There are three shorter (2.77 Å) and one longer (3.01 Å) Rh(1)-Zn(1) bond length. All Rh(1)-Pb(1) bond lengths are 2.69 Å. Zn(1) is bonded in a distorted single-bond geometry to one Cr(1), four equivalent Rh(1), and three equivalent Pb(1) atoms. All Zn(1)-Pb(1) bond lengths are 2.69 Å. Pb(1) is bonded in a 10-coordinate geometry to four equivalent Cr(1), three equivalent Rh(1), and three equivalent Zn(1) atoms.
