The conjugated homobimetallic palladium(II) complex [(L¹)Pd(qd)Pd(L¹)] (qd = quinonediimine) was obtained in a one-pot reaction by the in-situ oxidative complexation of 1,4-phenylenediamine with the palladium(II) complex [(L¹)Pd(MeCN)] (H₂L¹ = N,N′-bis(2-phenylethyl)-2,6-pyridinedicarboxamide) while in the absence of an additional ligand [(L¹)Pd(MeCN)] was converted to the amide-bridged macrocyclic tetramer [Pd(L¹)]₄.
