A novel high-nuclear nanosized cluster modified by conjugated organic ligands (pyridine and imidazole), [C5NH5](8)[C3H5N2](2){[C6NH5](9) [H31Mo2O24Co12(PO4)(23) (H2O)(4)]}center dot 12H(2)O (1), has been successfully isolated under hydrothermal conditions and structurally characterized. Compound 1 consists of 12 Co-II and 12 Mo-V ions linked by 23 {PO4} groups, exhibiting unprecedented nanosized ship-shaped clusters. The magnetic measurements reveal that compound 1 exhibits dominant antiferromagnetic interactions. Additionally, pyridine and imidazole ligands enhance the delocalized electron effects of clusters, and the third-order nonlinear optical response of compound 1 is excellent.
