BaMgGe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Ba(1) is bonded in a 9-coordinate geometry to four equivalent Mg(1) and five equivalent Ge(1) atoms. Mg(1) is bonded to four equivalent Ba(1) and four equivalent Ge(1) atoms to form a mixture of distorted edge and face-sharing MgBa4Ge4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to five equivalent Ba(1) and four equivalent Mg(1) atoms.
BaMgGe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Ba(1) is bonded in a 9-coordinate geometry to four equivalent Mg(1) and five equivalent Ge(1) atoms.
