BaPtNi4 crystallizes in the trigonal R3m space group. Ba(1) is bonded in a 16-coordinate geometry to three equivalent Pt(1), four equivalent Ni(2), and nine equivalent Ni(1) atoms. All Ba(1)-Pt(1) bond lengths are 3.09 Å. There are three shorter (3.03 Å) and one longer (3.45 Å) Ba(1)-Ni(2) bond length. There are six shorter (2.95 Å) and three longer (3.68 Å) Ba(1)-Ni(1) bond lengths. Pt(1) is bonded in a 12-coordinate geometry to three equivalent Ba(1), three equivalent Ni(2), and six equivalent Ni(1) atoms. All Pt(1)-Ni(2) bond lengths are 2.95 Å. There are three shorter (2.09 Å) and three longer (3.14 Å) Pt(1)-Ni(1) bond lengths. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 2-coordinate geometry to three equivalent Ba(1), two equivalent Pt(1), one Ni(2), and two equivalent Ni(1) atoms. The Ni(1)-Ni(2) bond length is 2.08 Å. Both Ni(1)-Ni(1) bond lengths are 1.20 Å. In the second Ni site, Ni(2) is bonded in a 10-coordinate geometry to four equivalent Ba(1), three equivalent Pt(1), and three equivalent Ni(1) atoms.
