摘要：
The syntheses of several Pd(II) complexes of 1,4,7-triazacyclononane, [9]aneN3, and the molecular structure of two complexes by X-ray diffraction are reported. The diprotonated bis complex, [Pd(HL)2](ClO4)4.H2O2, contains the ligands in the anti conformation and is structurally similar to the previously reported non-protonated PdL2(2+) in [PdL2]PF6. The acidity constants (pK(a)) of Pd(HL)24+ in 0.1 M ClO4- at 25-degrees-C are 2.40 and 4.72, respectively. The structure of the protonated mono complex, [PdHLBr2]ClO4, is also determined.
