MgPd2Ag crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two MgPd2Ag ribbons oriented in the (1, 0, 0) direction. Mg is bonded in a linear geometry to two equivalent Pd atoms. Both Mg–Pd bond lengths are 2.45 Å. Pd is bonded in a linear geometry to one Mg and one Ag atom. The Pd–Ag bond length is 2.66 Å. Ag is bonded in a linear geometry to two equivalent Pd atoms.
Mg2PdAg is Heusler-like structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Mg is bonded in a body-centered cubic geometry to four equivalent Pd and four equivalent Ag atoms. All Mg–Pd bond lengths are 2.78 Å. All Mg–Ag bond lengths are 2.88 Å. Pd is bonded in a body-centered cubic geometry to eight equivalent Mg atoms. Ag is bonded in a body-centered cubic geometry to eight equivalent Mg atoms.
