Mn2AsP is Modderite-derived structured and crystallizes in the orthorhombic Pmc2_1 space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent As(1) and four equivalent P(1) atoms to form a mixture of distorted face, corner, and edge-sharing MnAs2P4 octahedra. The corner-sharing octahedral tilt angles are 51°. In the second Mn site, Mn(2) is bonded in a 6-coordinate geometry to four equivalent As(1) and two equivalent P(1) atoms. As(1) is bonded in a 6-coordinate geometry to two equivalent Mn(1) and four equivalent Mn(2) atoms. P(1) is bonded in a 6-coordinate geometry to two equivalent Mn(2) and four equivalent Mn(1) atoms.

The corner-sharing octahedral tilt angles are 51°. There is one shorter (2.36 Å) and one longer (2.45 Å) Mn(1)-As(1) bond length. There are two shorter (2.38 Å) and two longer (2.39 Å) Mn(1)-P(1) bond lengths. In the second Mn site, Mn(2) is bonded in a 6-coordinate geometry to four equivalent As(1) and two equivalent P(1) atoms. There are two shorter (2.40 Å) and two longer (2.45 Å) Mn(2)-As(1) bond lengths. There is one shorter (2.26 Å) and one longer (2.60 Å) Mn(2)-P(1) bond length. As(1) is bonded in a 6-coordinate geometry to two equivalent Mn(1) and four equivalent Mn(2) atoms. P(1) is bonded in a 6-coordinate geometry to two equivalent Mn(2) and four equivalent Mn(1) atoms.
