| Abstract: Two inorganic-organic hybrids,[(4-I-Anis)([18]crown-6)]2[SMo12O40]·CH3CN (1) and[(3-F-4-Cl-Anis)2(DB[30]crown-10)] [SMo12O40]·2CH3CN (2) (4-I-Anis=4-iodoanilinium; 3-F-4-Cl-Anis=3-fluoro-4-chloroanilinium; DB[30]crown-10=dibenzo[30]crown-10) have been synthesized and characterized by infrared spectrum (IR), elemental analysis (EA), powder XRD, thermogravimetric (TG), solid state diffuse reflectance spectra (DRS) and X-ray diffraction. Crystals 1 and 2 are constructed through noncovalent bonding interaction, and the polyoxo-metalates 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 crystal 1, each polyoxoanion is surrounded by six monovalent supramolecular cations (4-I-Anis)([18]crown-6) and forms hexagonal arrangement in bc plane. In crystal 2, each polyoxoanion is surrounded by four large supramolecular cations (3-F-4-Cl-Anis)2(DB[30]crown-10) and forms tetragonal arrangement in bc plane. TG measurement indicated that hydrogen bonding interaction plays an important role in maintaining the structural stability of crystals 1 and 2. DRS indicated that there exists charge-transfer interaction between[SMo12O40]2- polyoxoanions and crown ether based supramolecular cations in crystals 1 and 2. |
