Zirconium Arene-Phosphonates:  Chemical and Structural Characterization of 2-Naphthyl- and 2-Anthracenylphosphonate Systems

Several new zirconium phosphonates incorporating naphthalene and anthracene ring systems and having the general formula Zr(O3PR)1(O3PR‘)1 [R and R‘ = −C10H7, −C14H9, −OC4H9, and −OC2H5] have been synthesized. These compounds were chemically characterized using thermal gravimetric analysis (percentag...

Description
Summary:Several new zirconium phosphonates incorporating naphthalene and anthracene ring systems and having the general formula Zr(O3PR)1(O3PR‘)1 [R and R‘ = −C10H7, −C14H9, −OC4H9, and −OC2H5] have been synthesized. These compounds were chemically characterized using thermal gravimetric analysis (percentage of organic content), infrared spectroscopy (presence of the desired organic functional groups), and solid-state 31P NMR (phosphorus environments), while the structural parameters were determined using X-ray powder diffraction (interlayer d spacings). The d spacings of the zirconium bis(phosphonates) correlate well with a simple predictive model based on the effective length of the organic functional group. The zirconium mixed phosphonates examined are single-phase structures with random mixtures of the organic moieties within the interlayer and possess d spacings that are between those of the two parent zirconium bis(phosphonates).
