The material structure described by Sr3In4Pb crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 11-coordinate geometry to four equivalent In(1), five equivalent In(2), and two equivalent Pb(1) atoms. In the second Sr site, Sr(2) is bonded in a 9-coordinate geometry to two equivalent In(2), four equivalent In(1), and three equivalent Pb(1) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 10-coordinate geometry to two equivalent Sr(2), four equivalent Sr(1), three equivalent In(2), and one Pb(1) atom. In the second In site, In(2) is bonded in a 10-coordinate geometry to one Sr(2), five equivalent Sr(1), one In(2), and three equivalent In(1) atoms. Pb(1) is bonded in a 9-coordinate geometry to three equivalent Sr(2), four equivalent Sr(1), and two equivalent In(1) atoms. is represented by the CIF file [CIF]
