Synthesis of Cu(II)-Organophosphonate Framework with Predefined Void Spaces
2015
Here we report the first utilization of the novel methane tetra-p-phenylphosphonic acid (MTPPA) ligand for the preparation of metal complexes with Cu(II). The hydrothermal and solvothermal reactions of tetratopic MTPPA as a bridging ligand in conjunction with the square pyramidal {Cu(terpy)}2+ and {Cu2(pbterpy)}4+, (where terpy = 2,2′:6′,2″-Terpyridine and pbterpy = 4′,4″″-(1,4-Phenylene)bis(2,2′:6′,2″-terpyridine)) as prefixed corner building units have produced one-dimensional [{Cu(terpy)}2(MTPPA-H5) (MTPPA-H6)]·(4.25H2O)(H3O) (1) and two-dimensional [{Cu2(pbterpy)}MTPPA-H4] (2), respectively. The structures were characterized by single crystal X-ray diffraction and TGA.
