The structure described by EuPt4B crystallizes in the hexagonal P6/mmm space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 18-coordinate geometry to twelve equivalent Pt(1) and six equivalent B(1) atoms. In the second Eu site, Eu(2) is bonded in a distorted hexagonal planar geometry to six equivalent Pt(2) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted L-shaped geometry to two equivalent Eu(1), two equivalent Pt(2), and two equivalent B(1) atoms. In the second Pt site, Pt(2) is bonded in a 12-coordinate geometry to three equivalent Eu(2), three equivalent Pt(2), and six equivalent Pt(1) atoms. B(1) is bonded in a 6-coordinate geometry to three equivalent Eu(1) and six equivalent Pt(1) atoms. is represented by the CIF card [CIF]
