In the second Rh site, Rh(2) is bonded in a 6-coordinate geometry to four equivalent La(1), two equivalent Ge(2), and four equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Rh(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to four equivalent La(1), one Rh(2), two equivalent Rh(1), and two equivalent Ge(3) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to four equivalent La(1), one Rh(1), two equivalent Rh(2), and two equivalent Ge(2) atoms.
