ZnP2 crystallizes in the tetragonal P4_32_12 space group. Zn(1) is bonded to two equivalent P(1) and two equivalent P(2) atoms to form ZnP4 tetrahedra that share corners with four equivalent Zn(1)P4 tetrahedra, corners with four equivalent P(1)Zn2P2 tetrahedra, and corners with four equivalent P(2)Zn2P2 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to two equivalent Zn(1) and two equivalent P(2) atoms to form PZn2P2 tetrahedra that share corners with four equivalent Zn(1)P4 tetrahedra, corners with four equivalent P(1)Zn2P2 tetrahedra, and corners with four equivalent P(2)Zn2P2 tetrahedra. In the second P site, P(2) is bonded to two equivalent Zn(1) and two equivalent P(1) atoms to form distorted PZn2P2 tetrahedra that share corners with four equivalent Zn(1)P4 tetrahedra, corners with four equivalent P(1)Zn2P2 tetrahedra, and corners with four equivalent P(2)Zn2P2 tetrahedra.

There is one shorter (2.37 Å) and one longer (2.38 Å) Zn(1)-P(1) bond length. There is one shorter (2.35 Å) and one longer (2.40 Å) Zn(1)-P(2) bond length. There are two inequivalent P sites. In the first P site, P(1) is bonded to two equivalent Zn(1) and two equivalent P(2) atoms to form PZn2P2 tetrahedra that share corners with four equivalent Zn(1)P4 tetrahedra, corners with four equivalent P(1)Zn2P2 tetrahedra, and corners with four equivalent P(2)Zn2P2 tetrahedra. There is one shorter (2.17 Å) and one longer (2.21 Å) P(1)-P(2) bond length. In the second P site, P(2) is bonded to two equivalent Zn(1) and two equivalent P(1) atoms to form distorted PZn2P2 tetrahedra that share corners with four equivalent Zn(1)P4 tetrahedra, corners with four equivalent P(1)Zn2P2 tetrahedra, and corners with four equivalent P(2)Zn2P2 tetrahedra.
