Two series of chiral organometallic Donor-π-Acceptor chromophores derived from [Fe2(η5-C5H 5)2(CO)2(μ-CO)(μ-C-CH 3)]+ [BF4]- have been synthesised. In the first series (S)-(-)-2-methoxymethyl pyrrolidine acts as the chiral donor end group and in the second series 1,1′-binaphthyl acts as the chiral π-bridging unit. The nonlinear optical properties of these compounds were measured by the Kurtz powder technique and by hyper-Raleigh scattering. β-values of up to 964 × 10-30 esu were obtained for a member of the first series. Single crystal X-ray studies of [Fe2 (η5-C5H5)2(CO) 2(μ-CO)(μ-C-CH3)]+ [BF4]-, [Fe2(η5-C 5H4CH3)2(CO)2 (μ-CO)(μ-(E)-C-CH=CH-2 -(5-piperidin-1-yl-thiophene))]+ [BF4]- and [Fe2(η5- C5H4CH3)2(CO)2 (μ-CO)(μ-(E)-C-CH=2-(naphthalene))]+ [BF4] - are reported.
