A series of neutral 16-electron square pyramidal ruthenium(II) complexes of the general formula [Ru(POCOP)(X)(CO)] (X = Cl, H) have readily been obtained in good yields from [RuCl2(COD)]n and different POCOP pincer ligands based on the naphthoresorcinate backbone. The molecular structure of two of the compounds was unequivocally determined by single-crystal X-ray diffraction, showing different stereochemistries upon the coordination of chloride or hydride ligand. The observed discrepancies are explained by DFT calculations. The regiospecific η6-coordination of a second 12-electron organometallic fragment on the exo aromatic ring of the POCOP pincer ligand was achieved under mild conditions, and the corresponding [(MLn)Ru(POCOP)(X)(CO)]PF6 (MLn = [RuCp]+, [RuCp*]+ and [FeCp*]+) bimetallic sandwich-like species were obtained as air-stable solids.
