The compound described by K3Cu3P2 crystallizes in the trigonal R-3m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 10-coordinate geometry to three equivalent K(2), six equivalent Cu(1), and four equivalent P(1) atoms. In the second K site, K(2) is bonded in a 18-coordinate geometry to six equivalent K(1), six equivalent Cu(1), and six equivalent P(1) atoms. Cu(1) is bonded in a distorted linear geometry to two equivalent K(2), four equivalent K(1), and two equivalent P(1) atoms. P(1) is bonded in a 7-coordinate geometry to three equivalent K(2), four equivalent K(1), and three equivalent Cu(1) atoms. is represented by the CIF file [CIF]
