EuMn2P2 crystallizes in the trigonal P-3m1 space group. Eu(1) is bonded to six equivalent P(1) atoms to form EuP6 octahedra that share corners with twelve equivalent Mn(1)P4 tetrahedra, edges with six equivalent Eu(1)P6 octahedra, and edges with six equivalent Mn(1)P4 tetrahedra. Mn(1) is bonded to four equivalent P(1) atoms to form MnP4 tetrahedra that share corners with six equivalent Eu(1)P6 octahedra, corners with six equivalent Mn(1)P4 tetrahedra, edges with three equivalent Eu(1)P6 octahedra, and edges with three equivalent Mn(1)P4 tetrahedra. The corner-sharing octahedral tilt angles range from 23-50°. P(1) is bonded in a 7-coordinate geometry to three equivalent Eu(1) and four equivalent Mn(1) atoms.

Eu(1) is bonded to six equivalent P(1) atoms to form EuP6 octahedra that share corners with twelve equivalent Mn(1)P4 tetrahedra, edges with six equivalent Eu(1)P6 octahedra, and edges with six equivalent Mn(1)P4 tetrahedra. All Eu(1)-P(1) bond lengths are 2.97 Å. Mn(1) is bonded to four equivalent P(1) atoms to form MnP4 tetrahedra that share corners with six equivalent Eu(1)P6 octahedra, corners with six equivalent Mn(1)P4 tetrahedra, edges with three equivalent Eu(1)P6 octahedra, and edges with three equivalent Mn(1)P4 tetrahedra. The corner-sharing octahedral tilt angles range from 23-50°. There is one shorter (2.34 Å) and three longer (2.37 Å) Mn(1)-P(1) bond lengths. P(1) is bonded in a 7-coordinate geometry to three equivalent Eu(1) and four equivalent Mn(1) atoms.
