Structural diversity of zinc(ii) coordination polymers with octafluorobiphenyl-4,4′-dicarboxylate based on mononuclear, paddle wheel and cuboidal units

We present a series of six novel Zn(ii) complexes containing anions of perfluorinated biphenyl-4,4′-dicarboxylate (oFBPDC2?). Among them are the 0D complex [Zn(eg)3](oFBPDC) (eg = ethylene glycol), the 1D [Zn(H2O)(ur)(oFBPDC)] (ur = urotropine) and [Zn(CH3OH)2(CH3OCH2CH2OH)(oFBPDC)] and the 2D layered [Zn2(CH3CN)2(oFBPDC)2]·2C6H6·2CH3CN, [Zn2(H2O)2(oFBPDC)2]·4(CH3)2CO, [{Zn4(μ3-OCH3)4}(CH3OH)4(oFBPDC)2]·[{Zn4(μ3-OCH3)4}(H2O)(CH3OH)3(oFBPDC)2]·13CH3OH. The latter coordination polymer is built up by unique Zn4(OCH3)4 cuboidal units. The complexes are characterized by single-crystal X-ray diffraction, FT-IR, elemental analysis, and TGA. Investigation of the CO2 adsorption at 195 K on [Zn2(CH3CN)2(oFBPDC)2] and [Zn2(H2O)2(oFBPDC)2] of the layered polymeric structure revealed that they have BET surface areas of 334.8 and 150.6 m2 g?1, respectively.

Synthesis of Octafluorobiphenyl-4,4′-dicarboxylic acid and photoluminescent compounds based thereon

Octafluorobiphenyl-4,4′-dicarboxylic acid (H2L) and its complexes with Tb(III) and Eu(III) [Ln2(H2O)4(L)3·3H2O and Ln2(phen)2(L)3·2H2O] have been prepared; their structure has been elucidated from IR spectroscopy and X-ray diffraction analysis data. Thermal properties of the compounds have been studied. The complexes of Tb(III) and Eu(III) exhibit green and red photoluminescence, respectively.
