The reaction of [PdClMe(Me2NCH2CH2NMe2)] with bis(2-pyridylmethyl)amine, bpma, gave the methylpalladium complex [PdMe(bpma)]Cl, which could be converted to the triflate or tetrafluoroborate salt by reaction with AgOTf or AgBF4. Further reaction of [PdMe(bpma)]OTf with B(C6F5)3 or HOTf gave the complex [Pd2(micro-OH)(bpma)2](OTf)3, which contains a bridging hydroxo ligand and no other bridging ligand, and whose structure contains an unexpectedly large Pd-O-Pd angle of 141.2(3) degrees. This complex acts as a model for complexes proposed to be formed during hydrolysis in aqueous solution of biologically active compounds such as cisplatin.
