Abstract: Two isolated organic-inorganic pentavanadate-based hybrids, [H2N (CH3)2]6.34 [VV (μ3-O)4VI4V O5 (SO4)4]·(SO4)0.67·(DMF)· [HN (CH3)2]1.66 (1) and [(HN)2 (CH2)2 (CH3)4] [VV (μ3-O)4V4IVO5 (SO4)4] [H2N (CH3)2]3·(DMF)· [HN (CH3)2]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.

Key words: Pentavanadate, Third-order nonlinear optical property, Crystal structure
