摘要

A lead(II) orotate complex [Pb(HOr)(H2O)]_n (1), (H3Or = orotic acid) was synthesized under hydrothermal condition and characterized by X-ray diffraction, IR, solid-state photoluminescence and thermogravimet-ric analysis. Lead atom in 1 is in a holodirected eight-coordinated polyhedron and the orotate ligand exhibits a new and unique hexametaltic coordination mode. The lead complex shows a 6,6-connected (4~8, 6~6, 8)(4~(13), 6~2) topology. The complex exhibits photoluminescence at 546 nm (λ_(ex) = 350 nm).
