Abstract: The title compound, [Rh₂(C₂H₃O₂)₄(C₂₁H₂₃NO)₂], is a centrosymmetric carboxylate-bridged dirhodium dimer, with each Rh^II ion in a slightly distorted octahedral coordination environment. One axial bond involves the oxo O atom of the 1-(adamant-1-yliminiomethyl)-2-naphtholate ligand, with a longer than normal Rh-O bond distance which is likely to be due to the bond-lengthening effect of the Rh-Rh bond trans to this O atom. A strong intramolecular hydrogen bond exists between the H atom of the imino N atom and the oxo O atom of the ligand. In addition, the 1-(adamant-1-yliminiomethyl)-2-naphtholate ligand shows delocalization of [pi] -electron density over the sequence of five atoms that extends from the N atom to the O atom.
