The structure described by K2NiP2 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to six equivalent P(1) atoms. In the second K site, K(2) is bonded in a 8-coordinate geometry to two equivalent Ni(1) and six equivalent P(1) atoms. Ni(1) is bonded in a 4-coordinate geometry to two equivalent K(2) and four equivalent P(1) atoms. P(1) is bonded in a 9-coordinate geometry to three equivalent K(1), three equivalent K(2), two equivalent Ni(1), and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
