The compound described by Sr4Au9In13 crystallizes in the hexagonal P-6m2 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 12-coordinate geometry to two equivalent Au(2), four equivalent Au(1), two equivalent In(4), and four equivalent In(1) atoms. In the second Sr site, Sr(2) is bonded in a 6-coordinate geometry to six equivalent Au(3) atoms. There are three inequivalent Au sites. In the first Au site, Au(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), one In(4), two equivalent In(1), and two equivalent In(3) atoms. In the second Au site, Au(2) is bonded in a 8-coordinate geometry to two equivalent Sr(1), two equivalent In(1), and four equivalent In(2) atoms. In the third Au site, Au(3) is bonded in a 9-coordinate geometry to two equivalent Sr(2), one In(2), two equivalent In(3), and four equivalent In(1) atoms. There are four inequivalent In sites. In the first In site, In(1) is bonded to two equivalent Sr(1), one Au(1), one Au(2), and two equivalent Au(3) atoms to form distorted InSr2Au4 tetrahedra that share corners with two equivalent In(3)Au4 tetrahedra, corners with five equivalent In(1)Sr2Au4 tetrahedra, edges with two equivalent In(3)Au4 tetrahedra, edges with three equivalent In(1)Sr2Au4 tetrahedra, and  a faceface with one In(1)Sr2Au4 tetrahedra. In the second In site, In(2) is bonded in a 5-coordinate geometry to one Au(3) and four equivalent Au(2) atoms. In the third In site, In(3) is bonded to two equivalent Au(1) and two equivalent Au(3) atoms to form InAu4 tetrahedra that share corners with four equivalent In(3)Au4 tetrahedra, corners with four equivalent In(1)Sr2Au4 tetrahedra, and edges with four equivalent In(1)Sr2Au4 tetrahedra.
