Pd15P2 crystallizes in the trigonal R-3 space group. There are four inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 1-coordinate geometry to one Pd(3), one Pd(4), and one P(1) atom. In the second Pd site, Pd(2) is bonded in a 1-coordinate geometry to one Pd(4), two equivalent Pd(3), and one P(1) atom. In the third Pd site, Pd(3) is bonded in a 10-coordinate geometry to one Pd(3), three equivalent Pd(1), and six equivalent Pd(2) atoms. In the fourth Pd site, Pd(4) is bonded in a cuboctahedral geometry to six equivalent Pd(1) and six equivalent Pd(2) atoms. P(1) is bonded in a 6-coordinate geometry to three equivalent Pd(1) and three equivalent Pd(2) atoms.
