The title N-heterocyclic carbene (NHC)-palladium complex, [PdBr2(C9H12N4)], an important precursor for catalytic reactions, exhibits a slightly distorted square-planar geometry at the Pd center, with two Br atoms in cis position, and is isostructural with the Pt analog [Muehlhofer, Strassner, Herdtweck & Hermann (2002). J. Organomet. Chem. 660, 121-126].
