Abstract

The synthesis of three new valent-averaged tetracarboxylatodiruthenium (II,III) complexes, [Ru₂(1-naphthylacetate)₄(H ₂O)₂](PF₆)×4THF, 1×4THF, [Ru ₂(2-naphthoate)₄(THF)₂](PF₆) ×3THF, 2×3THF, and [Ru₂(coumarin-3-carboxylate) ₄(MeOH)₂](PF₆)×MeOH×H₂O, 3×MeOH×H₂O, was accomplished using a well documented carboxylate exchange reaction. All three complexes were thoroughly characterized using infrared and UV-Vis spectroscopies, elemental analysis and X-ray diffraction. Due to the extended π-systems present, two of the complexes, 2×3THF and 3×MeOH×H₂O, display extensive π-stacking in two dimensions, with similar interactions notably absent in 1×4THF due to the perpendicular orientation of the naphthyl rings. Modest H-bonding is seen in complexes 1×4THF and 3×MeOH×H ₂O. As these types of complexes are noted secondary building units (SBU's) in the construction of metal-organic frameworks (MOF's), the significance of these interactions in stabilizing even larger, supramolecular structures, are noted.
