Sr Li Ta In
LiSrTaIn crystallizes in the trigonal R3m space group. Li(1) is bonded in a distorted single-bond geometry to three equivalent Ta(1) and one In(1) atom. All Li(1)-Ta(1) bond lengths are 2.99 Å. The Li(1)-In(1) bond length is 2.21 Å. Sr(1) is bonded to one Ta(1) and three equivalent In(1) atoms to form distorted SrTaIn3 trigonal pyramids that share  a cornercorner with one In(1)Sr3LiTa trigonal bipyramid, corners with three equivalent Ta(1)SrLi3In trigonal bipyramids, and corners with six equivalent Sr(1)TaIn3 trigonal pyramids. The Sr(1)-Ta(1) bond length is 2.21 Å. All Sr(1)-In(1) bond lengths are 2.99 Å. Ta(1) is bonded to three equivalent Li(1), one Sr(1), and one In(1) atom to form distorted TaSrLi3In trigonal bipyramids that share corners with six equivalent Ta(1)SrLi3In trigonal bipyramids, corners with three equivalent Sr(1)TaIn3 trigonal pyramids, and edges with three equivalent In(1)Sr3LiTa trigonal bipyramids. The Ta(1)-In(1) bond length is 2.21 Å. In(1) is bonded to one Li(1), three equivalent Sr(1), and one Ta(1) atom to form distorted InSr3LiTa trigonal bipyramids that share corners with six equivalent In(1)Sr3LiTa trigonal bipyramids,  a cornercorner with one Sr(1)TaIn3 trigonal pyramid, and edges with three equivalent Ta(1)SrLi3In trigonal bipyramids.
