Pr(ZnGa)2 crystallizes in the tetragonal I4/mmm space group. Pr(1) is bonded in a 16-coordinate geometry to eight equivalent Zn(1) and eight equivalent Ga(1) atoms. Zn(1) is bonded in a 9-coordinate geometry to four equivalent Pr(1), one Zn(1), and four equivalent Ga(1) atoms. Ga(1) is bonded to four equivalent Pr(1) and four equivalent Zn(1) atoms to form a mixture of distorted corner, edge, and face-sharing GaPr4Zn4 tetrahedra.
