摘要

Two novel metal-organic coordination polymers[Zn2(PDC)2·H2O]n(1)and[Zn2La2(OH)(NO3)(PDC)4-(H2O)6·2H2O]n(2)(PDC=pyridine-2,3-dicarboxylic acid)have been synthesized by hydrothermal pretreatment and cooling-down crystallization.X-ray diffraction analyses reveal that they posses the 3D frameworks.Frame work 1 has been accomplished by using building blocks Zn-PDC with beautiful undulances.Frame work 2 iS a new 3d-4f heterometallic polymer with a distinctive mono-and dinuclear mixed one sinusoidal-like wave viewed along the b axis.
