Abstract

The title methylene-bridged bis-N-heterocyclic carbene (NHC) palladium complex exhibits a distorted square-planar geometry around the palladium center, with the six-membered chelate ring adopting a boat conformation.

The structure of the title solvated bis-N-heterocyclic carbene palladium(II) complex, [PdI₂(C₁₉H₃₂N₄O₂)₂·C₂H₆O, exhibits a slightly distorted square-planar coordination at the palladium(II) atom, with the six-membered chelate ring adopting a boat conformation. One disordered ethanol solvent molecule was co-crystallized. There are intermolecular O—H⋯O hydrogen bonds in the structure. The chiral centers of the precursor imidazolium salt was preserved during the metalation process.
