N2 - 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-2N,C1]rhodium(III), [RhCl(C11H8N)2(CH3CN)] (1), thyminate(1-) and methanol, namely (OC-6-42)-methanol(5-methyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin- 1-ido-N1)bis[2-(pyridin-2-yl)phenyl-2N,C1]rhodium(III), [Rh(C11H8N)2(C5H5N2O2)(CH3OH)]CH3OH0.5H2O (2), and thyminate( 1-) and ethanol, namely (OC-6-42)-ethanol(5-methyl-2,4-dioxo- 1,2,3,4-tetrahydropyrimidin-1-ido-N1)bis[2-(pyridin-2-yl)phenyl-2N,C1]rhodium( III), [Rh(C11H8N)2(C5H5N2O2)(C2H5OH)]C2H5OH (3), are reported. The acetonitrile complex, 1, is isostructural with the IrIII analog. In complexes 2 and 3, the monodeprotonated thyminate (Hthym-) ligand coordinates to the RhIII atom through the N atom, and the resulting Rh-N(Hthym) bond lengths are relatively long [2.261 (2) and 2.252 (2) A ° 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.
