MnNiP2 is Modderite-derived structured and crystallizes in the orthorhombic Pmc2_1 space group. Mn(1) is bonded in a 6-coordinate geometry to two equivalent P(1) and four equivalent P(2) atoms. Ni(1) is bonded in a 6-coordinate geometry to two equivalent P(2) and four equivalent P(1) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 6-coordinate geometry to two equivalent Mn(1) and four equivalent Ni(1) atoms. In the second P site, P(2) is bonded in a 6-coordinate geometry to four equivalent Mn(1) and two equivalent Ni(1) atoms.
MnNiP2 is Modderite-derived structured and crystallizes in the orthorhombic Pmc2_1 space group. Mn(1) is bonded in a 6-coordinate geometry to two equivalent P(1) and four equivalent P(2) atoms. There is one shorter (2.21 Å) and one longer (2.33 Å) Mn(1)-P(1) bond length. There are two shorter (2.29 Å) and two longer (2.36 Å) Mn(1)-P(2) bond lengths. Ni(1) is bonded in a 6-coordinate geometry to two equivalent P(2) and four equivalent P(1) atoms. There is one shorter (2.24 Å) and one longer (2.37 Å) Ni(1)-P(2) bond length.
