文摘

Eight new zinc diphosphonates, [NaZn(O₃P(CH₂)₂PO₃H)] (1), [K₂Zn₂(HO₃P(CH₂)₂PO₃H)(O₃P(CH₂)₂PO₃)] (2), [(NH₄)(H₃N(CH₂)₂NH₃)_0.5Zn₃(O₃P(CH₂)₂PO₃)₂] (3), [(NH₄)₂Zn₃(O₃P(CH₂)₃PO₃)₂] (4), [(H₃N(CH₂)₄NH₃)_0.5Zn(O₃P(CH₂)₃PO₃H)] (5), [KZn(O₃P(CH₂)₄PO₃H)] (6), [KZn(HO₃P(CH₂)₄PO₃H)(Cl)] (7), and [NH₄Zn(O₃P(CH₂)₄PO₃H)] (8), have been successfully synthesizedunder mixed solvothermal conditions and characterized by X-ray single-crystal diffraction together with elemental analysis, infraredspectroscopy, thermogravimetric analysis, and powder X-ray diffraction. In 1 and 2, 1,2-ethylenediphosphonate groups combinecations (Na⁺, K⁺) and Zn-O-P layers into 3D frameworks, while in 3 and 4, ethylene and propylene groups are enclosed in novel3D Zn-O-P frameworks, respectively, which possess 8-membered ring (8MR) and 12MR channels. In 5-8, Zn-O-P infinitechains are pillared by 1,3-propylene- and 1,4-butylenediphosphonate groups into hybrid layers. It is interesting that in 7 K-Cllamellae link the Zn-O-P hybrid layer to form a 3D sandwichlike framework. If 1 is synthesized with commercial fluorescentwhitener (disodium 4,4'-bis(2-sulfonatostyryl)biphenyl) in the initial reaction mixture, it exhibits bright purple-blue luminescencewith a short lifetime. Photoluminescent properties of 4 and 8 are also discussed.
