A 3D Zn(II) coordination polymer (CP) {[Zn(L)(0.5)(1,4-bib)].H2O)(n), (1), (H4L = 1,2,4,5-cyclohexanetetracar-boxylic acid, 1,4-bib = 1,4-bis(1H-imidazol-1-yl)benzene) with flower-like morphology was synthesized under ultrasonic irradiation and characterized by elemental analysis, IR, powder X-ray diffraction and scanning electron microscopy. CP 1 exhibits a 4-connected 3-fold interpenetrating mog framework. The thermal stability and luminescence properties of nano 1 were investigated. Moreover, nanostructures of zinc(II) oxide were obtained by calcination of nano 1 at 600 degrees C under air atmospheres. Further, nano 1 shows a remarkable photocatalytic activity for degradation of MB under UV irradiation, a possible photocatalytic mechanism is proposed in terms of the HOMO-LUMO gap and the associated UV light-induced transitions in the compound.
