MOFs Based on Silver Terephthalate and Malonate
摘要
Abstract
Polymeric silver terephthalate [Ag2(ter)] (1) (ter2– = O2C-C6H4-CO2) and malonate [Ag2(malo)] (2) (malo2– = O2C-CH2-CO2) are obtained and characterized by the elemental analysis and IR spectroscopy. When heated, these complexes dissolve in pyridine (py) or its derivatives. The crystals of MOFs [Ag(py)4](Hter) (3a), [Ag2(3-Me-py)4(ter)] (4a), [Ag2(3-Me-py)4(malo)] (5a) are obtained from solutions. Single crystals are analyzed by X-ray diffraction, however, they rapidly decompose with a loss of py molecules if they are isolated from the mother liquor or slightly heated. Stable products of 3a, 4a, 5a desolvation and decoordination are [Ag2(py)2.8](Hter)2 (3), [Ag2(3-Me-py)1.3(ter)] (4), [Ag2(3-Me-py)2.9(malo)] (5).
