摘要

Two isolated organic-inorganic pentavanadate-based hybrids,[H2N(CH3)2]6.34[VⅤ(μ3-O)4VⅣ4O5(SO4)4]·(SO4)0.67·(DMF)· [HN(CH3h] 1.66(1) and [(HN)2(CH2)2(CH3)4] [VⅤ(μ3-O)4V4ⅣO5(SO4)4] [H2N(CH3)2]3(DMF)·[HN(CH3H3]0.5(2)(DMF=N,N-dimethylformamide) have been synthesized under solvothermal conditions and structurally characterized.In compound 1,three adjacent basic units form a triangle type cluster.The symmetric double-layer exists in compound 2.The study of the third-order nonlinear optical(NLO) properties for the two compounds demonstrates that the two-photon absorption(TPA) cross-section σ values of compounds 1 and 2 are 1372 and 1228 GM,respectively,indicating that both compounds may have potential application in optical field.
