摘　　要：Employing 4,4＇-trimethylenedipyridine as a template, a new two-dimensional zinc phosphite （4,4＇-（CsH4N）2（CH2）3）＂ [Zna（HPO3）4] has been prepared at room temperature and characterized by single-crystal X-ray diffraction, FTIR, elemental analysis, powder X-ray diffraction, and thermogravimetric analysis. The compound crystallizes in the monoclinic space group P21/c, with cell parameters, a = 9.3309（19）/k, b = 14.798（3）A, c = 33.637（7）/k, β= 91.11（3）°, V = 4643.8（16） nm3 and Z = 4. The connectivity of the ZnO4 tetrahedra and HPO3 pseudo pyramids results in infinite corner-sharing 4-membered ring chains as second building units which are further linked by Zn-O-P bonds to form a 2-D layer that with interesting 8-membered ring channels along the [100] direction. The diprotonated 4,4＇-trimethylenedipyridine molecules sit in the middle of the layers along the [100] direction and interact with the framework via hydrogen bonds.Employing 4,4-trimethylenedipyridine as a template,a new two-dimensional zinc phosphite (4,4-(C5H4N)2(CH2)3)· [Zn3(HPO3)4 ] has been prepared at room temperature and characterized by single-crystal X-ray diffraction,FTIR,elemental analysis,powder X-ray diffraction,and thermogravimetric analysis.The compound crystallizes in the monoclinic space group P2 1 /c,with cell parameters,a=9.3309(19),b=14.798(3),c=33.637(7),β=91.11(3),V=4643.8(16) nm 3 and Z=4.The connectivity of the ZnO4 tetrahedra and HPO 3 pseudo pyramids results in infinite corner-sharing 4-membered ring chains as second building units which are further linked by Zn O P bonds to form a 2-D layer that with interesting 8-membered ring channels along the [100] direction.The diprotonated 4,4-trimethylenedipyridine molecules sit in the middle of the layers along the [100] direction and interact with the framework via hydrogen bonds.
