Abstract
A novel two-dimensional Zn(II) coordination polymer [Zn(II) CP], [{Zn(L)Zn(OAc–)(µ-OAc–)}4]n· 2nCH3CH2OH has been self-assembled from Zn(OAc)2·2H2O. It contains pyridine-terminal salamo-type ligand H2L. Structure of the product has been determined. The Zn(II)CP contains two kinds of Zn(II) ions of different coordination modes. The Zn1 center is characterized by five-coordinated triangular biconical geometry. The Zn2 center is a six-coordinated octahedral center. Using these as junction points and the fully deprotonated ligand (L)2– moieties containing pyridine-terminal as a linker, the 2-D coordination polymer with two kinds of different pores [27.47 × 11.77(23) Å2; 11.97 × 4.51(17) Å2] has been obtained. The Zn(II) CP can fluoresce green and be used in fluorescent materials. Short-range interactions on Zn(II) CP surface have been studied by Hirshfeld surface analysis.
