The di-μ-carboxylato complexes <2> (CH2C9H6N = 8-quinolylmethyl, R = Me or CF3) react in methanol with NaOH(aq) (1:1 molar ratio) to give the corresponding mixed hydroxocarboxylato-bridged complexes <2(μ-OH)(μ-O2CR)> (R = Me 1 or CF3 2).The reactions of 1 or 2 with arylamines or thiols (1:1 molar ratio) yielded the corresponding amido- or thiolato-carboxylato complexes <2(μ-O2CMe)(μ-NHR)> (R = Ph 3, p-MeC6H4 4 or p-NO2C6H4 5) or <2(μ-O2CR)(μ-SR')> (R = Me, R' = Et 6, t-Bu 7, Ph 8 or p-MeC6H4 9; R = CF3, R' = t-Bu 10).The 1H NMR data indicate a cis arrangement of the CH2C9H6N ligands.The crystal structure of complex 10 has been determined.It confirms the cis relationship of the CH2C9H6N ligands.The co-ordination at each palladium atom is approximately square planar and the oxygen atoms of the trifluoroacetate ligands are trans to carbon.The Pd2(μ-OCOCF3)(μ-SBut) core is quite bent with an angle of 55 deg between the two palladium co-ordination planes.
