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

The X-ray structures of 2a and 4c are reported.
