Abstract

We present a series of six novel Zn(II) complexes containing anions of perfluorinated biphenyl-4,4′-dicarboxylate (oFBPDCБ2−). 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, [{Zn43-OCH3)4}(CH3OH)4(oFBPDC)2]·[{Zn43-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.
