The compound described by LaPt3Al2 crystallizes in the hexagonal P6/mmm space group. La(1) is bonded in a 18-coordinate geometry to twelve equivalent Pt(1) and six equivalent Al(1) atoms. Pt(1) is bonded in a distorted square co-planar geometry to four equivalent La(1) and four equivalent Al(1) atoms. Al(1) is bonded in a 6-coordinate geometry to three equivalent La(1) and six equivalent Pt(1) atoms. is represented by the CIF card [CIF]
