【 摘 要 】

Single crystals of nanocomposite [GaO₄Al₁₂(OH)₂₄(H₂O)₁₂][Al(OH)₆Mo₆O₁₈]₂(OH)·30H₂O, 2, were obtained by the reaction between [GaO₄Al₁₂(OH)₂₄(H₂O)₁₂]⁷⁺ and [Mo₇O₂₄]^6- clusters in an aqueous solution, analogously to the [AlO₄Al₁₂(OH)₂₄(H₂O)₁₂][Al(OH)₆Mo₆O₁₈]₂(OH)·29.5H₂O nanocomposite, 1. The crystal structure of 2 was determined by single crystal x-ray diffraction; space group C2/c (No. 15), a = 27.418(2) �?, b = 15.647(2) �?, c = 23.960(4) �?, �? = 102.850(9)�?, V = 10,021.5(20) �?³ , Z = 4. Detailed analysis of the structural data show that the clusters are held by intimate hydrogen bondings of the surface O^2- and OH^- groups of the clusters as well as the ionic interactions between the oppositely charged cluster ions.
