Analysis of the main structural trends for biscyclometalated dinuclear rhodium compounds of general formula Rh2(O2CR)2(PC)2 · 2H2O

A new series of dinuclear rhodium (II) compounds with two cyclometalated aryl phosphines, two bridging acetate groups and two water molecules in the axial positions, has been obtained. The crystal structures for these compounds have been determined by X-ray diffraction and the main structural trends, bond lengths, bond angles and torsion angles have been analyzed, and have also been compared with the structural parameters of analogous complexes previously described in the literature.
