Sr2Rh2In3 crystallizes in the monoclinic C2/m space group. Sr(1) is bonded in a 12-coordinate geometry to four equivalent Rh(1), three equivalent In(1), and five equivalent In(2) atoms. Rh(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), two equivalent In(1), and three equivalent In(2) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 4-coordinate geometry to six equivalent Sr(1) and four equivalent Rh(1) atoms. In the second In site, In(2) is bonded in a 3-coordinate geometry to five equivalent Sr(1) and three equivalent Rh(1) atoms.
Sr2Rh2In3 crystallizes in the monoclinic C2/m space group. Sr(1) is bonded in a 12-coordinate geometry to four equivalent Rh(1), three equivalent In(1), and five equivalent In(2) atoms. There are a spread of Sr(1)-Rh(1) bond distances ranging from 3.06-3.54 Å. There is one shorter (3.56 Å) and two longer (3.58 Å) Sr(1)-In(1) bond lengths. There are a spread of Sr(1)-In(2) bond distances ranging from 3.41-3.60 Å. Rh(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), two equivalent In(1), and three equivalent In(2) atoms. Both Rh(1)-In(1) bond lengths are 2.70 Å. There are two shorter (2.81 Å) and one longer (2.87 Å) Rh(1)-In(2) bond length. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 4-coordinate geometry to six equivalent Sr(1) and four equivalent Rh(1) atoms. In the second In site, In(2) is bonded in a 3-coordinate geometry to five equivalent Sr(1) and three equivalent Rh(1) atoms.
