MgPm2 crystallizes in the tetragonal I4/mmm space group. The structure is two-dimensional and consists of two MgPm2 sheets oriented in the (0, 0, 1) direction. Mg is bonded in a body-centered cubic geometry to eight equivalent Pm atoms. All Mg–Pm bond lengths are 3.36 Å. Pm is bonded in a 8-coordinate geometry to four equivalent Mg atoms.
MgPm2 crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of two MgPm2 sheets oriented in the (1, 0, 0) direction. Mg is bonded in a body-centered cubic geometry to eight Pm atoms. There are a spread of Mg–Pm bond distances ranging from 3.36–3.40 Å. There are two inequivalent Pm sites. In the first Pm site, Pm is bonded in a 4-coordinate geometry to four equivalent Mg atoms. In the second Pm site, Pm is bonded in a 12-coordinate geometry to four equivalent Mg atoms.
MgPm2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Mg is bonded in a body-centered cubic geometry to eight Pm atoms. There are a spread of Mg–Pm bond distances ranging from 3.33–3.40 Å. There are two inequivalent Pm sites. In the first Pm site, Pm is bonded in a 12-coordinate geometry to six equivalent Mg and four equivalent Pm atoms. There are two shorter (3.71 Å) and two longer (3.73 Å) Pm–Pm bond lengths. In the second Pm site, Pm is bonded in a 12-coordinate geometry to two equivalent Mg and ten Pm atoms. There are four shorter (3.47 Å) and two longer (3.80 Å) Pm–Pm bond lengths.
