The material described by Ba(NiP2)2 crystallizes in the orthorhombic Immm space group. Ba(1) is bonded in a 24-coordinate geometry to eight equivalent Ni(1), eight equivalent P(1), and eight equivalent P(2) atoms. Ni(1) is bonded to four equivalent Ba(1), two equivalent P(1), and two equivalent P(2) atoms to form a mixture of distorted corner, edge, and face-sharing NiBa4P4 tetrahedra. There are two inequivalent P sites. In the first P site, P(2) is bonded in a 2-coordinate geometry to four equivalent Ba(1) and two equivalent Ni(1) atoms. In the second P site, P(1) is bonded in a 2-coordinate geometry to four equivalent Ba(1) and two equivalent Ni(1) atoms. is represented by the CIF card [CIF]
