The material described by BaLa2PtO5 crystallizes in the tetragonal P4/mbm space group. Ba(1) is bonded in a distorted q6 geometry to two equivalent O(1) and eight equivalent O(2) atoms. La(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. Pt(1) is bonded in a square co-planar geometry to four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ba(1) and four equivalent La(1) atoms to form OBa2La4 octahedra that share corners with six equivalent O(1)Ba2La4 octahedra, corners with sixteen equivalent O(2)Ba2La3Pt octahedra, and faces with eight equivalent O(2)Ba2La3Pt octahedra. The corner-sharing octahedral tilt angles range from 0-61°. In the second O site, O(2) is bonded to two equivalent Ba(1), three equivalent La(1), and one Pt(1) atom to form distorted OBa2La3Pt octahedra that share corners with four equivalent O(1)Ba2La4 octahedra, corners with thirteen equivalent O(2)Ba2La3Pt octahedra, edges with five equivalent O(2)Ba2La3Pt octahedra, faces with two equivalent O(1)Ba2La4 octahedra, and faces with three equivalent O(2)Ba2La3Pt octahedra. The corner-sharing octahedral tilt angles range from 0-76°. is represented by the CIF file [CIF]
