The material structure described by InSn4 is Hg_xSn-derived structured and crystallizes in the orthorhombic Cmmm space group. In(1) is bonded to four equivalent In(1) and four equivalent Sn(1) atoms to form InIn4Sn4 hexagonal bipyramids that share corners with four equivalent In(1)In4Sn4 hexagonal bipyramids, corners with four equivalent Sn(2)Sn8 hexagonal bipyramids, edges with two equivalent Sn(2)Sn8 hexagonal bipyramids, edges with six equivalent In(1)In4Sn4 hexagonal bipyramids, and edges with sixteen equivalent Sn(1)In2Sn6 hexagonal bipyramids. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to two equivalent In(1), two equivalent Sn(2), and four equivalent Sn(1) atoms to form SnIn2Sn6 hexagonal bipyramids that share corners with two equivalent Sn(2)Sn8 hexagonal bipyramids, corners with six equivalent Sn(1)In2Sn6 hexagonal bipyramids, edges with seven equivalent Sn(1)In2Sn6 hexagonal bipyramids, edges with eight equivalent In(1)In4Sn4 hexagonal bipyramids, and edges with nine equivalent Sn(2)Sn8 hexagonal bipyramids. In the second Sn site, Sn(2) is bonded to two equivalent Sn(1) and six equivalent Sn(2) atoms to form SnSn8 hexagonal bipyramids that share corners with two equivalent In(1)In4Sn4 hexagonal bipyramids, corners with two equivalent Sn(1)In2Sn6 hexagonal bipyramids, corners with four equivalent Sn(2)Sn8 hexagonal bipyramids,  an edgeedge with one In(1)In4Sn4 hexagonal bipyramid, edges with nine equivalent Sn(1)In2Sn6 hexagonal bipyramids, and edges with fourteen equivalent Sn(2)Sn8 hexagonal bipyramids. is represented by the CIF file [CIF]
