Synthesis and crystal structure of [1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene](isocyanato- κ N)gold(I)

The title complex, [Au(NCO)(C27H36N2)], was synthesized by ligand metathesis from [1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene]gold(I) chloride and sodium cyanate in anhydrous tetrahydrofuran and crystallized from toluene at 233   K in the orthorhombic space group P212121, as a neutral complex with the central Au atom di-coordinated by an N-heterocyclic carbene [Au — C = 1.963   (2)   Å ] and an isocyanate [Au — N 1.999   (2)   Å ] ligands, with a linear CAuNCO moiety. The crystal packing is consolidated by C — H...O hydrogen bonds.
