A new 1D supramolecular involving two different ligands, {[Zn(GB)(2)]center dot(mu-bpe)(3)} (n) (ClO4)(2n) center dot nH(2)O (GB = 2-guanidinobenzimidazole and bpe = 1,2-bis(4-pyridyl)ethylene, has been synthesised, characterized by elemental analysis, IR-, H-1 NMR-, C-13 NMR spectroscopy. The thermal stability of compound {[Zn(GB)(2)]center dot(mu-bpe)(3)} (n) (ClO4)(2n) center dot nH(2)O was studied by thermal gravimetric and differential thermal analyses. The single crystal X-ray analysis shows that the complex is a one-dimensional polymer involving macrocycle rings as a result of non-covalent bridging bpe ligands via N-H center dot center dot center dot N and N center dot center dot center dot N interactions, N-H center dot center dot center dot bpe center dot center dot center dot bpe center dot center dot center dot H-N, with the basic repeating {[Zn(GB)(2)](mu-bpe)(3)}(ClO4)(2)center dot H2O units and by connecting [Zn(GB)(2)](2+) nodes. ZnO nanoparticles were obtained by calcination of compound {[Zn(GB)(2)]center dot(mu-bpe)(3)} (n) (ClO4)(2n) center dot nH(2)O at 500 A degrees C in air. The nanoparticles were characterized by X-ray diffraction and scanning electron microscopy.
