The aminocarbyne CN(Et)Me>(CO)2(cp)> 1 (cp = η-C5H5) reacts with (tht = tetrahydrothiophene) and CuCl to give the adducts (C6F5)(CO)2(cp)> 2 and Cl(CO)2(cp)>2> 3 respectively which have been structurally characterized by X-ray diffraction.Complex 2 crystallizes in space group P, a = 9.840(5), b = 11.577(6), c = 8.296(6) Angstroem, α = 99.03(5), β = 91.01(6), γ = 81.92(4) deg, Z = 2.Complex 3 crystallizes in space group P21/a, a = 7.788(2), b = 14.880(5), c = 11.712(5) Angstroem, β = 95.35(3) deg , Z = 2.Both adducts exhibit a molecule of 1 bonded to Au(C6F5) or Cu2Cl2 fragments, respectively, through one of the W-C(carbyne) ? bonds.A WCM ring is formed in which 1 preserves most of its identity and the coinage metals attain their preferred electron counts.The cationic Group 11 fragments (M = Cu, Ag or Au) also react with complex 1 to form (CO)2(cp)>2>(1+) 5; when M = Au NMR spectroscopy indicates that in addition to the trinuclear species 5, the dimetallacyclopropene (CO)2(cp)(PPh3)>(1+) 4 is also present.All these adducts have been spectroscopically characterised.
