Ca La Tc Sn
CaLaTcSn crystallizes in the trigonal R3m space group. Ca(1) is bonded to one Tc(1) and three equivalent Sn(1) atoms to form distorted CaTcSn3 trigonal pyramids that share  a cornercorner with one Sn(1)Ca3LaTc trigonal bipyramid, corners with three equivalent Tc(1)CaLa3Sn trigonal bipyramids, and corners with six equivalent Ca(1)TcSn3 trigonal pyramids. The Ca(1)-Tc(1) bond length is 2.19 Å. All Ca(1)-Sn(1) bond lengths are 2.99 Å. La(1) is bonded in a 4-coordinate geometry to three equivalent Tc(1) and one Sn(1) atom. All La(1)-Tc(1) bond lengths are 2.99 Å. The La(1)-Sn(1) bond length is 2.19 Å. Tc(1) is bonded to one Ca(1), three equivalent La(1), and one Sn(1) atom to form distorted TcCaLa3Sn trigonal bipyramids that share corners with six equivalent Tc(1)CaLa3Sn trigonal bipyramids, corners with three equivalent Ca(1)TcSn3 trigonal pyramids, and edges with three equivalent Sn(1)Ca3LaTc trigonal bipyramids. The Tc(1)-Sn(1) bond length is 2.19 Å. Sn(1) is bonded to three equivalent Ca(1), one La(1), and one Tc(1) atom to form distorted SnCa3LaTc trigonal bipyramids that share corners with six equivalent Sn(1)Ca3LaTc trigonal bipyramids,  a cornercorner with one Ca(1)TcSn3 trigonal pyramid, and edges with three equivalent Tc(1)CaLa3Sn trigonal bipyramids.
