Al Zn Pb
ZnAlPb crystallizes in the trigonal R3m space group. Zn(1) is bonded in a hexagonal planar geometry to three equivalent Al(1) and three equivalent Pb(1) atoms. All Zn(1)-Al(1) bond lengths are 2.70 Å. All Zn(1)-Pb(1) bond lengths are 2.70 Å. Al(1) is bonded to three equivalent Zn(1) and four equivalent Pb(1) atoms to form distorted AlZn3Pb4 hexagonal pyramids that share corners with three equivalent Pb(1)Al4Zn3 hexagonal pyramids, corners with six equivalent Al(1)Zn3Pb4 hexagonal pyramids, edges with three equivalent Pb(1)Al4Zn3 hexagonal pyramids, and edges with six equivalent Al(1)Zn3Pb4 hexagonal pyramids. There are three shorter (2.72 Å) and one longer (3.38 Å) Al(1)-Pb(1) bond length. Pb(1) is bonded to three equivalent Zn(1) and four equivalent Al(1) atoms to form distorted PbAl4Zn3 hexagonal pyramids that share corners with three equivalent Al(1)Zn3Pb4 hexagonal pyramids, corners with six equivalent Pb(1)Al4Zn3 hexagonal pyramids, edges with three equivalent Al(1)Zn3Pb4 hexagonal pyramids, and edges with six equivalent Pb(1)Al4Zn3 hexagonal pyramids.
