Abstract: Two new inorganic-organic hybrids[(3-F-4-MeAnis)(DB[18]crown-6)]2[Mo6O19]·2CH3CN (1) and[(2-F-4-MeAnis)([18]crown-6)]2[SMo12O40]·2CH3CN (2) (3-F-4-MeAnis=3-fluoro-4-methylanilinium, DB[18]crown-6=dibenzo[18]crown-6,2-F-4-MeAnis=2-fluoro-4-methylanilinium) have been synthesized and characterized by infrared spectrum (IR), elemental analysis (EA), thermosgravimetric analysis (TGA) and X-ray diffraction. Compounds 1 and 2 are constructed through noncovalent bonding interaction and the polyoxometalates (POMs) and supramolecular cation arrange alternately. Supramolecular cation forms through the N-H…O hydrogen bonding interaction between the nitrogen atom of anilinium and oxygen atoms of crown ether derivatives. In the crystals of 1 and 2, each polyoxoanion is surrounded by six supramolecular cations and forms hexagonal arrangement viewed along the a axis. Crystalline structure and TGA indicated that phenyl rings in DB[18]crown-6 plays an important role in maintaining the stability of compound 1. |
