Ba Li Hg Pt
LiBaPtHg crystallizes in the trigonal R3m space group. Li(1) is bonded in a distorted single-bond geometry to one Pt(1) and three equivalent Hg(1) atoms. The Li(1)-Pt(1) bond length is 2.06 Å. All Li(1)-Hg(1) bond lengths are 3.00 Å. Ba(1) is bonded to three equivalent Pt(1) and one Hg(1) atom to form distorted BaHgPt3 trigonal pyramids that share  a cornercorner with one Pt(1)Ba3LiHg trigonal bipyramid, corners with three equivalent Hg(1)BaLi3Pt trigonal bipyramids, and corners with six equivalent Ba(1)HgPt3 trigonal pyramids. All Ba(1)-Pt(1) bond lengths are 3.00 Å. The Ba(1)-Hg(1) bond length is 2.06 Å. Pt(1) is bonded to one Li(1), three equivalent Ba(1), and one Hg(1) atom to form distorted PtBa3LiHg trigonal bipyramids that share corners with six equivalent Pt(1)Ba3LiHg trigonal bipyramids,  a cornercorner with one Ba(1)HgPt3 trigonal pyramid, and edges with three equivalent Hg(1)BaLi3Pt trigonal bipyramids. The Pt(1)-Hg(1) bond length is 2.06 Å. Hg(1) is bonded to three equivalent Li(1), one Ba(1), and one Pt(1) atom to form distorted HgBaLi3Pt trigonal bipyramids that share corners with six equivalent Hg(1)BaLi3Pt trigonal bipyramids, corners with three equivalent Ba(1)HgPt3 trigonal pyramids, and edges with three equivalent Pt(1)Ba3LiHg trigonal bipyramids.
