摘要

The binuclear praseodymium(Ⅲ) complex with N-(1-carboxyethylidene)-salicylhydrazide (C10H10N2O4, H2L)determined by X-ray single crystal diffraction. The crystal complex crystallizes in the triclinic system with spacegroup P-1, and in the structure each Pr atom is 9-coordinated by carboxyl O and acyl O and azomethine N atoms oftwo tridentate ligands to form two stable five-membered rings sharing one side in keto-mode and two water mole-cules. The coordination polyhedron around Pr3+ was described as a monocapped square antiprism geometry. In anindividual molecule, four tridentate ligands were coordinated by two negative univalent (HL) and two bivalentforms (L) respectively. Two negative univalent ligands were coordinated via μ2-bridging mode.
