Summary Copper(I) trifluoromethanesulphonate and 5, 10, 15-trithia-cyclo-triveratrylene (Vn3S3, 3) react with CO in CHCl3 as solvent to yield a carbonyl complex which can be crystallised from EtOH in a CO atmosphere giving the complex [Cu(Vn3S3)(CO)]O3SCF3·0.5 EtOH (8), which was characterised by av(CO) absorption band at 2140 cm−1 indicating a weak back donation of copper(I). When (8) is heated in MeOH in an N2 atmosphere, complex [Cu(Vn3S3)(CH3OH)]O3SCF3·MeOH (15) is formed. X-ray analysis of (15) reveals a distorted tetrahedral coordination of the copper(I) ion with a strongly bonded methanol ligand (Cu−O 198 pm, Cu−S 229 pm).
