Be In Hg Pb
BeHgInPb crystallizes in the trigonal R3m space group. Be(1) is bonded in a distorted single-bond geometry to one In(1) atom. The Be(1)-In(1) bond length is 2.27 Å. Hg(1) is bonded in a distorted linear geometry to one In(1) and one Pb(1) atom. The Hg(1)-In(1) bond length is 2.27 Å. The Hg(1)-Pb(1) bond length is 2.27 Å. In(1) is bonded to one Be(1), one Hg(1), and three equivalent Pb(1) atoms to form distorted InBeHgPb3 trigonal bipyramids that share corners with six equivalent In(1)BeHgPb3 trigonal bipyramids and  a cornercorner with one Pb(1)In3Hg trigonal pyramid. All In(1)-Pb(1) bond lengths are 2.99 Å. Pb(1) is bonded to one Hg(1) and three equivalent In(1) atoms to form distorted PbIn3Hg trigonal pyramids that share  a cornercorner with one In(1)BeHgPb3 trigonal bipyramid and corners with six equivalent Pb(1)In3Hg trigonal pyramids.
