KNi2P crystallizes in the triclinic P1 space group. K(1) is bonded in a 8-coordinate geometry to four equivalent K(1), one Ni(1), one Ni(2), and two equivalent P(1) atoms. There are two shorter (2.88 Å) and two longer (3.59 Å) K(1)-K(1) bond lengths. The K(1)-Ni(1) bond length is 3.53 Å. The K(1)-Ni(2) bond length is 3.53 Å. There is one shorter (3.51 Å) and one longer (3.58 Å) K(1)-P(1) bond length. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a distorted single-bond geometry to one K(1) and one P(1) atom. The Ni(1)-P(1) bond length is 1.06 Å. In the second Ni site, Ni(2) is bonded in a single-bond geometry to one K(1) and one P(1) atom. The Ni(2)-P(1) bond length is 0.83 Å. P(1) is bonded in a 2-coordinate geometry to two equivalent K(1), one Ni(1), and one Ni(2) atom.
