a ClO3A new coordination polymer, {[Zn(bib)3 (CIO4)2)n(1)was prepared at room temperature by the reaction of appropriate salts of zinc(II) with the flexible linker ligands 1,4-bis(imidazolyl) butane )(bib).and methylimidazolyl)butane (bibMe) The compound was characterized by elemental analyses, IR spectroscopy and single crystal X-ray diffraction. In the polymeric structure of 1, the , Zn(II) ions lies on an inversion center and adopts the ZnN6 octahedral geometry. In compound 1,six bib ligands are coordinated to one central zinc(II) to form an open 3D 2-fold interpenetrating framework of the a-polonium (pcu) type topology
