A New 3D Supramolecular Network Formed by Zn3(2,6-Pyridinedicarboxylate)3Cl44- and 4-Carboxypyridinium

摘要

A new compound [Zn3(C7NO4H3)3Cl4]·[C6NO2H6]4·4H2O (I) has been synthesized and structurally characterized by X-ray crystallography.It crystallizes in monoclinic,space group C2/c with a=16.9018(14),b=12.6902(10),c=25.1170(2),β=90.54°,V=5387.0(8)3,Z=4,Zn3C45H41Cl4N7O24,Mr=1401.76,Dc=1.728 g/cm3,F(000)=2840,μ(MoKa)=1.615 mm-1,the R= 0.0758 and wR=0.2060 for 3468 observed reflections (I > 2σ(I)).Analysis of single-crystal X-ray diffraction data shows that compound I displays an interesting example of 3D supramolecular networks with perfect neutral and ionic hydrogen bonding array.
