Abstract

A new ligand, 4-(1,10-phenanthrolin-6-yl)-benzoic acid, has been synthesized and employed to prepare new inorganic coordination polymer compounds, M(C19H11N2O2)(2)center dot H2O] (M = Co, Mn). Both the compounds have identical structures formed by the connectivity between octahedral metal centers and the ligand, giving rise to a two-dimensional structure. The 2D structure is interpenetrated by identical units and forms a 2-fold interpenetrated structure. The lattice water molecules can be reversibly removed without altering the gross framework structure. The water removal has been investigated using in situ IR, PXRD, and in situ single crystal XRD studies. Pd nanoparticles, prepared employing known procedures, were incorporated within the compound. We have successfully encapsulated up to 6.8% of Pd with a particle size of 4.8 +/- 0.3 nm in the compound. The Pd@MOF compound was examined for homocoupling of aryl halides, resulting in good yields and recydability. Magnetic studies indicate antiferromagnetic behavior in both the compounds with good orbital contribution for the cobalt compound.
