The material described by Eu2Pt7ZnP3 crystallizes in the tetragonal I-4m2 space group. Eu(1) is bonded in a 15-coordinate geometry to two equivalent Pt(1), two equivalent Pt(2), five equivalent Pt(3), two equivalent P(2), and four equivalent P(1) atoms. There are four inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 12-coordinate geometry to two equivalent Eu(1), two equivalent Pt(4), four equivalent Pt(2), two equivalent Zn(1), and two equivalent P(1) atoms. In the second Pt site, Pt(2) is bonded in a 12-coordinate geometry to two equivalent Eu(1), two equivalent Pt(4), four equivalent Pt(1), two equivalent Zn(1), and two equivalent P(1) atoms. In the third Pt site, Pt(3) is bonded in a 7-coordinate geometry to five equivalent Eu(1), one P(1), and two equivalent P(2) atoms. In the fourth Pt site, Pt(4) is bonded to four equivalent Pt(1), four equivalent Pt(2), and four equivalent Zn(1) atoms to form distorted PtZn4Pt8 cuboctahedra that share corners with four equivalent Pt(4)Zn4Pt8 cuboctahedra, faces with four equivalent Pt(4)Zn4Pt8 cuboctahedra, and faces with four equivalent Zn(1)Pt12 cuboctahedra. Zn(1) is bonded to four equivalent Pt(1), four equivalent Pt(2), and four equivalent Pt(4) atoms to form ZnPt12 cuboctahedra that share corners with four equivalent Zn(1)Pt12 cuboctahedra, faces with four equivalent Pt(4)Zn4Pt8 cuboctahedra, and faces with four equivalent Zn(1)Pt12 cuboctahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 9-coordinate geometry to four equivalent Eu(1), one Pt(3), two equivalent Pt(1), and two equivalent Pt(2) atoms. In the second P site, P(2) is bonded in a 8-coordinate geometry to four equivalent Eu(1) and four equivalent Pt(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
