The material structure described by Eu2PtAs3 is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. Eu(1) is bonded to three equivalent Pt(1), three equivalent As(1), three equivalent As(2), and three equivalent As(3) atoms to form a mixture of edge and face-sharing EuAs9Pt3 cuboctahedra. Pt(1) is bonded in a 9-coordinate geometry to six equivalent Eu(1) and three equivalent As(2) atoms. There are three inequivalent As sites. In the first As site, As(1) is bonded in a 9-coordinate geometry to six equivalent Eu(1) and three equivalent As(3) atoms. In the second As site, As(2) is bonded in a 9-coordinate geometry to six equivalent Eu(1) and three equivalent Pt(1) atoms. In the third As site, As(3) is bonded in a 9-coordinate geometry to six equivalent Eu(1) and three equivalent As(1) atoms. is represented by the CIF card [CIF]
