Abstract: The substitution reaction of CpM (CO)3SnPh3 or CpM (CO)3SnPh2X (Cp=C5H4CH3, C5H4COCH3;M=Mo, W; X=Cl, Br) with HCl or HBr yielded trihalo- or mixed trihalostannane tungsten(molybdemun) bonded bimetallic complexes, which were character-ized by elementary analysis, 1H NMRand IR. Crystals of complex Cl3SnW(CO)3C5H4·COCH3 are monoclinic, space group P21/c, a=0.7686(3)nm, b=1.2622(2)nm, c=1.6022(2)nm, β=102.13(2)°, Z=4, μ=97.45cm-1, V=1. 5197(7)nm3. The bond dis-tance of Sn-Wbond is 0.27361(8)nm.
