Phosphine‐based coordination cages and nanoporous coordination polymers

AbstractRecent findings in the use of multidentate phosphines to synthesise porous coordination polymers (metal‐organic frameworks) and their possible precursor cages are reviewed. Additional recent investigations into using large adamantoid Age cages as polymer vertices in giant diamandoid structures are also presented. The results are discussed in terms of possible strategies for the controled synthesis of porous coordination polymers.

A novel organic/inorganic hybrid nanoporous material incorporating Keggin-type polyoxometalates

Tree novel nanoporous compounds, [Cu 3(TMA) 2(H 2O) 3] 4[{(CH 3) 4N} 2(H 2SiMo 12O 40)] ·≈40H 2O ( 1), [Cu 3(TMA) 2(H 2O) 3] 4[{(CH 3) 4N} 2(HPW 12O 40)] ·≈40H 2O ( 2), and [Cu 3(TMA) 2(H 2O) 3] 4[{(CH 3) 4N} 2(HPMo 6W 6O 40)] ·≈40H 2O ( 3) (TMA=acidtrimesic acid=1,3,5-benzentricaboxylate) have been synthesized via hydrothermal process, and characterized by X-ray structure analysis, IR and NMR spectroscopy, and thermogravimetry. All the compounds crystallize isostructurally consisting of a nanoporous coordination polymer framework [Cu 3(TMA) 2(H 2O) 3] n accommodating α-Keggin polyoxomolybdate and -tungstate anions. Results of the IR and 29Si and 31P MAS NMR spectra reveal the existence of α-Keggin species with no other impurity.
