Mononuclear palladium carbene complexes 2a – c and 3 derived from 1,1′‐methylenebis(4‐alkyl‐4,5‐dihydro‐1 H‐ 1,2,4‐triazole‐5‐ylidene) have been obtained by the reaction of 1,1′‐methylenebis(4‐alkyl‐1,2,4‐triazolium) diiodides 1a – d with palladium acetate under mild conditions. The mononuclear complexes 2a – c have been transformed into their corresponding trans ‐binuclear complexes 4a – c . All compounds were characterized by spectroscopic techniques and the dynamic behavior of 2a – c and 4a – c has been studied. The X‐ray structures of 2a and 4c are reported.
