摘要:
The reaction of [Ru(eta-Cp)(dppf)N-3] (1) with equimolar amount of SnBr2 yielded an interesting heterotrimetallic compound [Ru(eta-Cp)(dppf)SnBr3] (2) (dppf: 1,1'-bis-diphenylphosphinoferrocene). Compounds I and 2 were characterised by IR, NMR (H-1, C-13, P-31 and Sn-119), and 2, additionally, by Fe-57 and Sn-119 Mossbauer spectroscopy and X-ray crystallography. The latter results were as follows: monoclinic, C2/c, a = 32.8879(4) Angstrom, b = 11.9888(2) Angstrom, c = 20.8986(3) Angstrom, beta = 92.545(1)degrees, V = 8231.9(2) Angstrom(3), Z = 8.
