Synthesis, Crystal Structures and Properties of 1D Zinc(II) Coordination Polymer {[Zn(H2O)2(L)(phen)]•3H2O}n

A zinc polymer {[Zn(H2O)(2)(L)(phen)]center dot 3H(2)O}(n) (1, H2L=1-hydroxy-8-amino-naphthahne-3,6-disulfonic acid, phen=1,10-phenanthroline) has been synthesized and structurally characterized by elemental analysis, IR, UV, PL, TG and single crystal X-ray diffraction. The title complex crystallized in orthorhombic with space group Pnma, a=1.698 90(12) nm, b=0.661 88(11) nm, c=2.480 40(14) nm, V=2.789 1(5) nm(3), Z=4, M-r=634.92, D-c= 1.512 g.cm(-3), the final R=0.058 6, wR=0.121 4 for 1 994 observed reflections (I>2 sigma-(I)). In 1, L2- ligands bridge the six-coordinated zinc (II) ions forming 1D chains, which are further connected by intermolecular hydrogenbonding interactions, generating a 2D supramolecular network. Moreover, aromatic pi-pi stacking interactions between phenyl rings of L2- dianion and phenanthrolines were detected. CCDC: 900913.
