Materials Data on U(Ni2P)2 by Materials Project

Abstract

U(Ni2P)2 crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. U is bonded to twelve equivalent Ni and six equivalent P atoms to form distorted face-sharing UNi12P6 octahedra. There are eight shorter (3.07 Å) and four longer (3.09 Å) U–Ni bond lengths. There are two shorter (2.80 Å) and four longer (2.83 Å) U–P bond lengths. Ni is bonded in a 3-coordinate geometry to three equivalent U and three equivalent P atoms. There are two shorter (2.31 Å) and one longer (2.33 Å) Ni–P bond lengths. P is bonded in a 9-coordinate geometry to three equivalent U and six equivalent Ni atoms.
