The material structure described by UNi2P2 crystallizes in the tetragonal I4/mmm space group. U(1) is bonded in a 16-coordinate geometry to eight equivalent Ni(1) and eight equivalent P(1) atoms. Ni(1) is bonded to four equivalent U(1) and four equivalent P(1) atoms to form a mixture of distorted edge, corner, and face-sharing NiU4P4 tetrahedra. P(1) is bonded in a 9-coordinate geometry to four equivalent U(1), four equivalent Ni(1), and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
