Structural diversity and luminescence properties of three zinc coordination polymers based on bis(4-(1H-imidazol-1-yl)phenyl)methanone
Three zinc coordination polymers,{[Zn2(bipmo)2(ipa)2]·3H2O}n(1),{[Zn(bipmo)(5-OH-ipa)]DMA·H2O}n(2),and {[Zn(bipmo)(5-Me-ipa)]·H2O}n(3),where bipmo=bis(4-(1H-imidazol-1-yl)phenyl)methanone,H2ipa=isoph-thalic acid,5-OH-ipaH2=5-hydroxyisophthalic acid,5-Me-ipaH2=5-methylisophthalic acid,were synthesized under solvothermal conditions.These complexes have been characterized by elemental analyses,IR spectra,single-crystal X-ray diffraction,etc.Complex 1 shows a 2D 2-fold interpenetrating {44·62} network.Complex 2 displays a 2D uninodal framework with the {65·8} topology.Complex 3 reveals a 2D layer structure with {63} topology.The results indicate that the presence of a 5-substituted group in the isophthalate exerts a significant influence on the formation of the final structures.The luminescent properties of the complexes in the solid state have also been studied.CCDC:2297183,1;2297184,2;2297185,3.
