The structure described by Sr3LaCo2GaO9 crystallizes in the orthorhombic Fmm2 space group. There are three inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 9-coordinate geometry to one O(2), four equivalent O(1), and four equivalent O(3) atoms. In the second Sr site, Sr(2) is bonded in a 9-coordinate geometry to one O(1), four equivalent O(2), and four equivalent O(4) atoms. In the third Sr site, Sr(3) is bonded in a 6-coordinate geometry to two equivalent O(6) and four equivalent O(3) atoms. La(1) is bonded in a 10-coordinate geometry to two equivalent O(6), four equivalent O(4), and four equivalent O(5) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted T-shaped geometry to one O(5) and two equivalent O(6) atoms. In the second Co site, Co(2) is bonded to one O(2), one O(5), and four equivalent O(4) atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles are 15°. Ga(1) is bonded to one O(1) and four equivalent O(3) atoms to form distorted corner-sharing GaO5 square pyramids. There are six inequivalent O sites. In the first O site, O(5) is bonded in a distorted linear geometry to four equivalent La(1), one Co(1), and one Co(2) atom. In the second O site, O(6) is bonded in a distorted trigonal planar geometry to one Sr(3), one La(1), and one Co(1) atom. In the third O site, O(1) is bonded in a 6-coordinate geometry to one Sr(2), four equivalent Sr(1), and one Ga(1) atom. In the fourth O site, O(2) is bonded in a 6-coordinate geometry to one Sr(1), four equivalent Sr(2), and one Co(2) atom. In the fifth O site, O(3) is bonded to two equivalent Sr(1), two equivalent Sr(3), and two equivalent Ga(1) atoms to form a mixture of distorted edge, corner, and face-sharing OSr4Ga2 octahedra. The corner-sharing octahedral tilt angles are 22°. In the sixth O site, O(4) is bonded to two equivalent Sr(2), two equivalent La(1), and two equivalent Co(2) atoms to form a mixture of distorted edge, corner, and face-sharing OSr2La2Co2 octahedra. The corner-sharing octahedral tilt angles are 15°. is represented by the Crystallographic Information File (CIF) [CIF]
