| Abstract: A zinc polymer {[Zn(H2O)2(L)(phen)]·3H2O}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) nm3, Z=4, Mr=634.92, Dc=1.512 g·cm-3, the final R=0.058 6, wR=0.121 4 for 1 994 observed reflections (I>2σ(I)). In 1, L2- ligands bridge the six-coordinated zinc(Ⅱ) ions forming 1D chains, which are further connected by intermolecular hydrogen-bonding interactions, generating a 2D supramolecular network. Moreover, aromatic π-π stacking interactions between phenyl rings of L2- dianion and phenanthrolines were detected. CCDC: 900913. |
