ABSTRACT
The title complex, [Au(NCO)(C27H36N2)], was synthesized by ligand metathesis from [1,3-bis-(2,6-diiso-propyl-phen-yl)imidazol-2-yl-idene]gold(I) chloride and sodium cyanate in anhydrous tetra-hydro-furan and crystallized from toluene at 233â
K in the ortho-rhom-bic space group P212121, as a neutral complex with the central Au atom di-coordinated by an N-heterocyclic carbene [Au-C = 1.963â
(2)â
Å] and an iso-cyanate [Au-N 1.999â
(2)â
Å] ligands, with a linear CAuNCO moiety. The crystal packing is consolidated by C-Hâ¯O hydrogen bonds.
