The compound described by La7Pt3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent La sites. In the first La site, La(1) is bonded in a 3-coordinate geometry to three equivalent Pt(1) atoms. In the second La site, La(3) is bonded in a distorted water-like geometry to two equivalent Pt(1) atoms. In the third La site, La(2) is bonded in a 3-coordinate geometry to three equivalent Pt(1) atoms. Pt(1) is bonded in a 6-coordinate geometry to one La(1), two equivalent La(3), and three equivalent La(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
