The crystal structure described by La3Pt4 crystallizes in the trigonal R-3 space group. La(1) is bonded in a 9-coordinate geometry to one Pt(1), one Pt(2), and seven equivalent Pt(3) atoms. There are three inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 6-coordinate geometry to six equivalent La(1) atoms. In the second Pt site, Pt(2) is bonded in a 6-coordinate geometry to six equivalent La(1) atoms. In the third Pt site, Pt(3) is bonded in a 10-coordinate geometry to seven equivalent La(1) and three equivalent Pt(3) atoms. is represented by the CIF card [CIF]
