Al Zn Hg Pb
HgZnAlPb crystallizes in the trigonal R3m space group. Hg(1) is bonded in a 5-coordinate geometry to one Zn(1), three equivalent Al(1), and one Pb(1) atom. The Hg(1)-Zn(1) bond length is 2.42 Å. All Hg(1)-Al(1) bond lengths are 3.02 Å. The Hg(1)-Pb(1) bond length is 2.42 Å. Zn(1) is bonded to one Hg(1), one Al(1), and three equivalent Pb(1) atoms to form distorted ZnAlHgPb3 trigonal bipyramids that share corners with three equivalent Al(1)ZnHg3Pb3 hexagonal pyramids, corners with six equivalent Zn(1)AlHgPb3 trigonal bipyramids, and faces with three equivalent Al(1)ZnHg3Pb3 hexagonal pyramids. The Zn(1)-Al(1) bond length is 2.42 Å. All Zn(1)-Pb(1) bond lengths are 3.02 Å. Al(1) is bonded to three equivalent Hg(1), one Zn(1), and three equivalent Pb(1) atoms to form distorted AlZnHg3Pb3 hexagonal pyramids that share corners with three equivalent Zn(1)AlHgPb3 trigonal bipyramids, edges with six equivalent Al(1)ZnHg3Pb3 hexagonal pyramids, and faces with three equivalent Zn(1)AlHgPb3 trigonal bipyramids. All Al(1)-Pb(1) bond lengths are 3.15 Å. Pb(1) is bonded in a 7-coordinate geometry to one Hg(1), three equivalent Zn(1), and three equivalent Al(1) atoms.
