The structure described by Eu3Pt2 crystallizes in the trigonal R-3 space group. There are three inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in an octahedral geometry to six equivalent Pt(1) atoms. In the second Eu site, Eu(2) is bonded in a 6-coordinate geometry to six equivalent Pt(1) atoms. In the third Eu site, Eu(3) is bonded in a 5-coordinate geometry to five equivalent Pt(1) atoms. Pt(1) is bonded in a 9-coordinate geometry to one Eu(1), two equivalent Eu(2), five equivalent Eu(3), and one Pt(1) atom. is represented by the CIF card [CIF]
