The structure described by Ca2GaSn crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a 7-coordinate geometry to three equivalent Ga(1) and four equivalent Sn(1) atoms. In the second Ca site, Ca(2) is bonded in a 7-coordinate geometry to four equivalent Ga(1) and three equivalent Sn(1) atoms. Ga(1) is bonded in a 9-coordinate geometry to three equivalent Ca(1), four equivalent Ca(2), and two equivalent Sn(1) atoms. Sn(1) is bonded in a 9-coordinate geometry to three equivalent Ca(2), four equivalent Ca(1), and two equivalent Ga(1) atoms. is represented by the CIF card [CIF]
