Ti Ni Ni Rh
TiRhNi2 crystallizes in the monoclinic Cm space group. Ti(1) is bonded in a distorted single-bond geometry to one Rh(1) and one Ni(1) atom. The Ti(1)-Rh(1) bond length is 2.16 Å. The Ti(1)-Ni(1) bond length is 0.98 Å. Rh(1) is bonded in a distorted single-bond geometry to one Ti(1) and one Ni(2) atom. The Rh(1)-Ni(2) bond length is 3.14 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a single-bond geometry to one Ti(1) and one Ni(2) atom. The Ni(1)-Ni(2) bond length is 2.37 Å. In the second Ni site, Ni(2) is bonded to one Rh(1), one Ni(1), and six equivalent Ni(2) atoms to form a mixture of corner and edge-sharing NiNi7Rh hexagonal bipyramids. All Ni(2)-Ni(2) bond lengths are 2.67 Å.
