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=isophthalic 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.
