Synthesis and Characterisation of Palladium(II) Complexes with 1,2-bis(N-methylbenzimidazolyl)Benzene

Abstract

Palladium(II) salts react with a bidentate N-heterocycle 1,2-bis(N-methylbenzimidazolyl)benzene (N–N) to yield complexes of the composition PdX2(N–N) (X = Cl, Br or ClO4). A cationic complex, [Pd(cod)(cotl)]ClO4 (cod = 1,5–cyclooctadiene, cotl = cyclooctenyl, C8H13–) undergoes substitution of cod with N–N to produce [Pd(cotl)(N–N)]ClO4. Dihalobridged binuclear complexes [PdX(cotl)]2 (X = Cl or Br) react with N–N to give complexes of the types [Pd2Cl2(cotl)(N-N)]Cl and [{PdBr(cotl)}2(N–N)].
