Synthesis, Crystal Structures and Properties of 1D Zinc(II) Coordination Polymer {[Zn(H_2O)_2(L)(phen)].3H_2O}_n

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(I2σ(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 π-π stacking interactions between phenyl rings of L2-dianion and phenanthrolines were detected.CCDC: 900913.
