The six-membered cyclopalladated complex di-μ-acetato-bis[2-(2′-thiazolylmethyl)phenyl-C1,N]dipalladium(II), [{Pd(μ-O2CMe) (η2-bbt)}2] (η2-bbt = 2-(2′-thiazolylmethyl) phenyl-C1,N), has been prepared by the reaction of palladium(II) acetate and 2-benzylbenzothiazole. Its di-μ-halogeno analogues [{Pd(μ-K) (η2-bbt)}2], synthesised by the metathetical reaction with LiCL or NaX, undergo bridge-splitting reactions with some pyridine derivatives and thallium(I) acetylacetonate to yield corresponding mononuclear cyclopalladated complexes. The cyclopalladated feature and the six-membered structure have been confirmed by the 1H NMR spectra of the mononuclear pyridine complexes. Temperature-dependent 1H NMR spectra have been observed for [{Pd(μ-O2CMe) (η2-bbt)}2] and [Pd(acac) (η2-bbt)] and are attributed to inversions of acetato bridges and the boat-formed six-membered ring, respectively.
