The reaction of [Ru(η-Cp)(dppf)N 3] ( 1) with equimolar amount of SnBr 2 yielded an interesting heterotrimetallic compound [Ru(η-Cp)(dppf)SnBr 3] ( 2) (dppf: 1,1’-bis-diphenylphosphinoferrocene). Compounds 1 and 2 were characterised by IR, NMR ( 1H, 13C, 31P and 119Sn), and 2, additionally, by 57Fe and 119Sn Mössbauer spectroscopy and X-ray crystallography. The latter results were as follows: monoclinic, C2/ c, a=32.8879(4) Å, b=11.9888(2) Å, c=20.8986(3) Å, β=92.545(1)°, V=8231.9(2) Å 3, Z=8.
