5-Lithiated 4,4-dimethyl-2-(2-thienyl)oxazoline reacted by halide and tetrahydrothiophene (THT) substitution with [AuCl(THT)] to form a cyclic trinuclear compound (1) in satisfactory yield. Spectroscopic studies and single-crystal X-ray analyses clarified the bonding within the ring system. The structure determination of two THF solvates revealed differences in the supramolecular assembly of the constituting molecules.
