Crystal structures of bis­[2-(pyridin-2-yl)phenyl-κ(2) N,C (1)]rhodium(III) complexes containing an aceto­nitrile or monodentate thyminate(1−) ligand

The crystal structures of bis­[2-(pyridin-2-yl)phen­yl]rhodium(III) complexes with the metal in an octahedral coordination containing chloride and aceto­nitrile ligands, namely (OC-6-42)-aceto­nitrile­chlorido­bis­[2-(pyridin-2-yl)phenyl-κ(2) N,C (1)]rhodium(III), [RhCl(C(11)H(8)N)(2)(CH(3)CN)] (1), thyminate(1−) and methanol, namely (OC-6-42)-methanol(5-methyl-2,4-dioxo-1,2,3,4-tetrahydro­pyrimidin-1-ido-κN (1))bis­[2-(pyridin-2-yl)phenyl-κ(2) N,C (1)]rhodium(III), [Rh(C(11)H(8)N)(2)(C(5)H(5)N(2)O(2))(CH(3)OH)]·CH(3)OH·0.5H(2)O (2), and thy­min­ate(1−) and ethanol, namely (OC-6-42)-ethanol(5-methyl-2,4-dioxo-1,2,3,4-tetra­hydro­pyrimidin-1-ido-κN (1))bis[2-(pyridin-2-yl)phenyl-κ(2) N,C (1)]rhodium(III), [Rh(C(11)H(8)N)(2)(C(5)H(5)N(2)O(2))(C(2)H(5)OH)]·C(2)H(5)OH (3), are reported. The aceto­nitrile complex, 1, is isostructural with the Ir(III) analog. In complexes 2 and 3, the monodeprotonated thyminate (Hthym(−)) ligand coordinates to the Rh(III) atom through the N atom, and the resulting Rh—N(Hthym) bond lengths are relatively long [2.261 (2) and 2.252 (2) Å for 2 and 3, respectively] as compared to the Rh—N bonds in the related thyminate complexes. In each of the crystals of 2 and 3, the complexes are linked via a pair of inter­molecular N—H⋯O hydrogen bonds between neighbouring Hthym(−) ligands, forming an inversion dimer. A strong intra­molecular O—H⋯O hydrogen bond between the thyminate(1−) and alcohol ligands in mutually cis positions to each other is also observed.
