Hf2CoP is delta Molybdenum Boride-derived structured and crystallizes in the monoclinic P2_1/m space group. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 7-coordinate geometry to four equivalent Co(1) and three equivalent P(1) atoms. In the second Hf site, Hf(2) is bonded in a 7-coordinate geometry to three equivalent Co(1) and four equivalent P(1) atoms. Co(1) is bonded in a 9-coordinate geometry to three equivalent Hf(2), four equivalent Hf(1), and two equivalent P(1) atoms. P(1) is bonded in a 9-coordinate geometry to three equivalent Hf(1), four equivalent Hf(2), and two equivalent Co(1) atoms.
Hf2CoP is delta Molybdenum Boride-derived structured and crystallizes in the monoclinic P2_1/m space group. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 7-coordinate geometry to four equivalent Co(1) and three equivalent P(1) atoms. There are a spread of Hf(1)-Co(1) bond distances ranging from 2.61-2.86 Å. There are two shorter (2.72 Å) and one longer (2.78 Å) Hf(1)-P(1) bond length. In the second Hf site, Hf(2) is bonded in a 7-coordinate geometry to three equivalent Co(1) and four equivalent P(1) atoms. There are two shorter (2.62 Å) and one longer (2.86 Å) Hf(2)-Co(1) bond length. There are three shorter (2.71 Å) and one longer (2.75 Å) Hf(2)-P(1) bond length. Co(1) is bonded in a 9-coordinate geometry to three equivalent Hf(2), four equivalent Hf(1), and two equivalent P(1) atoms. Both Co(1)-P(1) bond lengths are 2.29 Å. P(1) is bonded in a 9-coordinate geometry to three equivalent Hf(1), four equivalent Hf(2), and two equivalent Co(1) atoms.
