The structure described by Tb2CrGe4 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 11-coordinate geometry to one Cr(1), two equivalent Ge(1), two equivalent Ge(3), two equivalent Ge(4), and four equivalent Ge(2) atoms. In the second Tb site, Tb(2) is bonded in a 10-coordinate geometry to two equivalent Ge(2), two equivalent Ge(3), two equivalent Ge(4), and four equivalent Ge(1) atoms. Cr(1) is bonded in a 5-coordinate geometry to one Tb(1), one Ge(1), two equivalent Ge(3), and two equivalent Ge(4) atoms. There are four inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Tb(1), four equivalent Tb(2), one Cr(1), and two equivalent Ge(2) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to two equivalent Tb(2), four equivalent Tb(1), and two equivalent Ge(1) atoms. In the third Ge site, Ge(3) is bonded in a 2-coordinate geometry to two equivalent Tb(1), two equivalent Tb(2), and two equivalent Cr(1) atoms. In the fourth Ge site, Ge(4) is bonded in a distorted bent 150 degrees geometry to two equivalent Tb(1), two equivalent Tb(2), and two equivalent Cr(1) atoms. is represented by the CIF file [CIF]
