The structure described by La3Pt2 crystallizes in the trigonal R-3 space group. There are three inequivalent La sites. In the first La site, La(1) is bonded in an octahedral geometry to six equivalent Pt(1) atoms. In the second La site, La(2) is bonded in a 6-coordinate geometry to six equivalent Pt(1) atoms. In the third La site, La(3) is bonded in a 5-coordinate geometry to five equivalent Pt(1) atoms. Pt(1) is bonded in a 8-coordinate geometry to one La(1), two equivalent La(2), and five equivalent La(3) atoms. is represented by the CIF card [CIF]
