U(Ni2P)2 crystallizes in the tetragonal P4_2/mnm space group. U(1) is bonded to six equivalent P(1) atoms to form a mixture of distorted corner and edge-sharing UP6 octahedra. The corner-sharing octahedral tilt angles are 40°. Ni(1) is bonded in a 3-coordinate geometry to three equivalent P(1) atoms. P(1) is bonded in a 9-coordinate geometry to three equivalent U(1) and six equivalent Ni(1) atoms.

The corner-sharing octahedral tilt angles are 40°. There are two shorter (2.78 Å) and four longer (2.84 Å) U(1)-P(1) bond lengths. Ni(1) is bonded in a 3-coordinate geometry to three equivalent P(1) atoms. There are two shorter (2.30 Å) and one longer (2.32 Å) Ni(1)-P(1) bond length. P(1) is bonded in a 9-coordinate geometry to three equivalent U(1) and six equivalent Ni(1) atoms.
