K Sb P P
KSbP2 crystallizes in the trigonal R3m space group. K(1) is bonded in a 2-coordinate geometry to one Sb(1), one P(2), and three equivalent P(1) atoms. The K(1)-Sb(1) bond length is 2.51 Å. The K(1)-P(2) bond length is 2.51 Å. All K(1)-P(1) bond lengths are 3.06 Å. Sb(1) is bonded in a 2-coordinate geometry to one K(1) and one P(1) atom. The Sb(1)-P(1) bond length is 2.51 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded to three equivalent K(1) and one Sb(1) atom to form distorted corner-sharing PK3Sb tetrahedra. In the second P site, P(2) is bonded in a single-bond geometry to one K(1) atom.
