In contrast to the case for 2, with an approximately staggered ferrocene conformation, the chloride complexes 3−5 exhibit a syn-periplanar ferrocene arrangement due to a Cl···H(C5H4) interaction in the solid and in solution. The related new compounds [(Cym)RuH(dppf)](PF6) (6) and trinuclear (μ-dpf)[(Cym)RuCl2)]2 (7−9) were also obtained and identified by 1H and 31P NMR spectroscopy.
