Sr V Ag Pb
SrVAgPb crystallizes in the trigonal R3m space group. Sr(1) is bonded to one Ag(1) and three equivalent Pb(1) atoms to form distorted SrAgPb3 trigonal pyramids that share  a cornercorner with one Pb(1)Sr3VAg trigonal bipyramid and corners with six equivalent Sr(1)AgPb3 trigonal pyramids. The Sr(1)-Ag(1) bond length is 2.12 Å. All Sr(1)-Pb(1) bond lengths are 2.99 Å. V(1) is bonded in a distorted single-bond geometry to one Pb(1) atom. The V(1)-Pb(1) bond length is 2.12 Å. Ag(1) is bonded in a distorted linear geometry to one Sr(1) and one Pb(1) atom. The Ag(1)-Pb(1) bond length is 2.12 Å. Pb(1) is bonded to three equivalent Sr(1), one V(1), and one Ag(1) atom to form PbSr3VAg trigonal bipyramids that share corners with six equivalent Pb(1)Sr3VAg trigonal bipyramids and  a cornercorner with one Sr(1)AgPb3 trigonal pyramid.
