Bis(1,3-dimesitylimidazolyl)gold(I) 2,4,8,10-tetraphenyl-1,3,5,7,9,11-hexaoxa-2,4,8,10-tetrabora-6-borataspiro[5.5]undecane

Abstract

The AuI atom in the title compound, [Au(C21H24N2)2](C24H20B5O6), adopts a slightly distorted linear AuC2 coordination geometry arising from its coordination by two mesitylenic N-heterocyclic carbene ligands, forming an overall cationic complex. The dihedral angle between the imidazole rings is 57.3 (6)°. In the crystal, the components are linked by weak C—H...O hydrogen bonds.
