Sr Sr Ti Rh
Sr2TiRh crystallizes in the trigonal R3m space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to one Sr(2), one Ti(1), and three equivalent Rh(1) atoms to form distorted SrSrTiRh3 trigonal bipyramids that share corners with six equivalent Sr(1)SrTiRh3 trigonal bipyramids and  a cornercorner with one Rh(1)Sr4 trigonal pyramid. The Sr(1)-Sr(2) bond length is 2.09 Å. The Sr(1)-Ti(1) bond length is 2.09 Å. All Sr(1)-Rh(1) bond lengths are 3.00 Å. In the second Sr site, Sr(2) is bonded in a distorted single-bond geometry to one Sr(1) and one Rh(1) atom. The Sr(2)-Rh(1) bond length is 2.09 Å. Ti(1) is bonded in a distorted single-bond geometry to one Sr(1) atom. Rh(1) is bonded to one Sr(2) and three equivalent Sr(1) atoms to form distorted RhSr4 trigonal pyramids that share  a cornercorner with one Sr(1)SrTiRh3 trigonal bipyramid and corners with six equivalent Rh(1)Sr4 trigonal pyramids.
