The compound crystallized in the Monoclinic space group P2（1）/c, with cell parameters, a=0.78410（9） nm, b=1.54744（2） nm, c=0.81418（1） nm, β=105.8150（1）°, V=0.95049（2） nm3 and Z=4. The connectivity of the ZnO4 tetrahedron and HPO3 pseudo pyramid resulted in inifinite corner-sharing 4-membered ring chains, which were further linked by the protonated amine molecules to form a 3D structure via hydrogen bonds. To the best of our knowledge, this is the first existence of a zincophosphite with the anionic framework composition of [Zn（HPO3）（H2PO3）]-. The compound exhibits intense photoluminescence at room temperature.展开更多
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 ...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.展开更多
