The structure described by Cu4SnP10 is Pb (Zr_0.50 Ti_0.48) O_3-like structured and crystallizes in the monoclinic Cm space group. There are three inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 7-coordinate geometry to one Cu(2), two equivalent Cu(3), one Sn(1), one P(2), and two equivalent P(5) atoms. In the second Cu site, Cu(2) is bonded in a 4-coordinate geometry to one Cu(1), one P(2), one P(4), one P(6), two equivalent P(5), and two equivalent P(7) atoms. In the third Cu site, Cu(3) is bonded in a distorted rectangular see-saw-like geometry to one Cu(1), one P(3), one P(5), one P(6), and one P(7) atom. Sn(1) is bonded in a 3-coordinate geometry to one Cu(1) and two equivalent P(3) atoms. There are seven inequivalent P sites. In the first P site, P(1) is bonded in a distorted trigonal pyramidal geometry to one P(4), one P(6), and two equivalent P(7) atoms. In the second P site, P(2) is bonded in a 6-coordinate geometry to one Cu(1), one Cu(2), one P(4), one P(6), and two equivalent P(5) atoms. In the third P site, P(3) is bonded in a 4-coordinate geometry to one Cu(3), one Sn(1), one P(4), and one P(7) atom. In the fourth P site, P(4) is bonded in a 6-coordinate geometry to one Cu(2), one P(1), one P(2), one P(6), and two equivalent P(3) atoms. In the fifth P site, P(5) is bonded in a 5-coordinate geometry to one Cu(1), one Cu(2), one Cu(3), one P(2), and one P(7) atom. In the sixth P site, P(6) is bonded in a 6-coordinate geometry to one Cu(2), two equivalent Cu(3), one P(1), one P(2), and one P(4) atom. In the seventh P site, P(7) is bonded in a 5-coordinate geometry to one Cu(2), one Cu(3), one P(1), one P(3), and one P(5) atom. is represented by the CIF file [CIF]
