PrMn2GeSi crystallizes in the tetragonal I4mm space group. Pr(1) is bonded in a 16-coordinate geometry to eight equivalent Mn(1), four equivalent Ge(1), and four equivalent Si(1) atoms. Mn(1) is bonded to four equivalent Pr(1), two equivalent Ge(1), and two equivalent Si(1) atoms to form a mixture of corner, face, and edge-sharing MnPr4Si2Ge2 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Pr(1), four equivalent Mn(1), and one Si(1) atom. Si(1) is bonded in a 9-coordinate geometry to four equivalent Pr(1), four equivalent Mn(1), and one Ge(1) atom.
