The structure described by Sr(GaTe2)2 crystallizes in the orthorhombic Cccm space group. Sr(1) is bonded in a 8-coordinate geometry to four equivalent Te(1) and four equivalent Te(2) atoms. Ga(1) is bonded to two equivalent Te(1) and two equivalent Te(2) atoms to form edge-sharing GaTe4 tetrahedra. There are two inequivalent Te sites. In the first Te site, Te(2) is bonded to two equivalent Sr(1) and two equivalent Ga(1) atoms to form a mixture of distorted corner and edge-sharing TeSr2Ga2 trigonal pyramids. In the second Te site, Te(1) is bonded to two equivalent Sr(1) and two equivalent Ga(1) atoms to form a mixture of corner and edge-sharing TeSr2Ga2 trigonal pyramids. is represented by the CIF card [CIF]
