Sr Li Nb Cd
LiSrNbCd crystallizes in the trigonal R3m space group. Li(1) is bonded in a distorted single-bond geometry to three equivalent Nb(1) and one Cd(1) atom. All Li(1)-Nb(1) bond lengths are 2.99 Å. The Li(1)-Cd(1) bond length is 2.18 Å. Sr(1) is bonded to one Nb(1) and three equivalent Cd(1) atoms to form distorted SrNbCd3 trigonal pyramids that share  a cornercorner with one Cd(1)Sr3LiNb trigonal bipyramid, corners with three equivalent Nb(1)SrLi3Cd trigonal bipyramids, and corners with six equivalent Sr(1)NbCd3 trigonal pyramids. The Sr(1)-Nb(1) bond length is 2.18 Å. All Sr(1)-Cd(1) bond lengths are 2.99 Å. Nb(1) is bonded to three equivalent Li(1), one Sr(1), and one Cd(1) atom to form distorted NbSrLi3Cd trigonal bipyramids that share corners with six equivalent Nb(1)SrLi3Cd trigonal bipyramids, corners with three equivalent Sr(1)NbCd3 trigonal pyramids, and edges with three equivalent Cd(1)Sr3LiNb trigonal bipyramids. The Nb(1)-Cd(1) bond length is 2.18 Å. Cd(1) is bonded to one Li(1), three equivalent Sr(1), and one Nb(1) atom to form distorted CdSr3LiNb trigonal bipyramids that share corners with six equivalent Cd(1)Sr3LiNb trigonal bipyramids,  a cornercorner with one Sr(1)NbCd3 trigonal pyramid, and edges with three equivalent Nb(1)SrLi3Cd trigonal bipyramids.
