Sr Ni Sn Rh
SrRhNiSn crystallizes in the trigonal R3m space group. Sr(1) is bonded in a single-bond geometry to four equivalent Rh(1), one Ni(1), and three equivalent Sn(1) atoms. There are three shorter (2.78 Å) and one longer (3.61 Å) Sr(1)-Rh(1) bond length. The Sr(1)-Ni(1) bond length is 0.89 Å. All Sr(1)-Sn(1) bond lengths are 2.83 Å. Rh(1) is bonded in a 10-coordinate geometry to four equivalent Sr(1), three equivalent Ni(1), and three equivalent Sn(1) atoms. All Rh(1)-Ni(1) bond lengths are 2.83 Å. All Rh(1)-Sn(1) bond lengths are 2.78 Å. Ni(1) is bonded in a single-bond geometry to one Sr(1), three equivalent Rh(1), and three equivalent Sn(1) atoms. All Ni(1)-Sn(1) bond lengths are 2.78 Å. Sn(1) is bonded in a 9-coordinate geometry to three equivalent Sr(1), three equivalent Rh(1), and three equivalent Ni(1) atoms.
