Cr5B2P crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 6-coordinate geometry to four equivalent B(1) and two equivalent P(1) atoms. In the second Cr site, Cr(2) is bonded to three equivalent B(1) and two equivalent P(1) atoms to form a mixture of distorted face, corner, and edge-sharing CrB3P2 trigonal bipyramids. B(1) is bonded in a 9-coordinate geometry to two equivalent Cr(1), six equivalent Cr(2), and one B(1) atom. P(1) is bonded in a 10-coordinate geometry to two equivalent Cr(1) and eight equivalent Cr(2) atoms.
Cr5B2P crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 6-coordinate geometry to four equivalent B(1) and two equivalent P(1) atoms. All Cr(1)-B(1) bond lengths are 2.22 Å. Both Cr(1)-P(1) bond lengths are 2.58 Å. In the second Cr site, Cr(2) is bonded to three equivalent B(1) and two equivalent P(1) atoms to form a mixture of distorted face, corner, and edge-sharing CrB3P2 trigonal bipyramids. There are two shorter (2.16 Å) and one longer (2.20 Å) Cr(2)-B(1) bond length. Both Cr(2)-P(1) bond lengths are 2.36 Å. B(1) is bonded in a 9-coordinate geometry to two equivalent Cr(1), six equivalent Cr(2), and one B(1) atom. The B(1)-B(1) bond length is 1.85 Å. P(1) is bonded in a 10-coordinate geometry to two equivalent Cr(1) and eight equivalent Cr(2) atoms.
