摘要:
Two isomeric dibenzo-O2S2 macrocycles L-1 and L-2 have been synthesised and their coordination chemistry towards palladium(II) has been investigated. Two-step approaches via reactions of 1:1-type complexes, [cis-Cl2LPd] (1a: L = L-1, 1b: L = L-2), with different O2S2 macrocycle systems (L-1 and L-2) have led to the isolation of the following bis(O2S2 macrocycle) palladium(II) complexes in the solid state: [Pd(L-1)(2)](ClO4)(2) (2a) and a mixture of [Pd(L-1)(2)](ClO4)(2) (2a) + [Pd(L-2)(2)](ClO4)(2) (2b).
