  名称：

  A New Dichroic, Nitroso‐Bridged Complex of Rhenium: Di‐μ ₂ ‐chloro[μ ₂ ‐(η ² ‐ N , O )‐ N , N ‐dimethyl‐4‐nitrosoaniline]bis[tricarbonylrhenium( I )]

  摘要：

  AbstractThe dimeric μ2‐amino‐phenoxy complexes of rhenium [(CO)3Re(μ2‐O∩NH2)]2 (1) do not react with the C‐nitroso compounds R−C6H4NO [R = NMe2 (2), H (2′)] in the presence of AlCl3 by a condensation reaction to give the desired azo dye complexes [(CO)3Re(μ2‐O∩N=NC6H4R)]2. Instead, they react to give the novel neutral η2‐N,O‐bridged C‐nitroso complexes [{CO)3ReCl}2ONC6H4R] (3, 3′) by means of a substitution reaction. Both complexes yield golden gleaming crystals, and their solutions are deeply blue (3) or violet (3′) due to the broad UV/Vis absorption at λ = 617 (3) and 505 nm (3′). Single crystals of 3, 3′ show nonlinear optical properties, they are dichroic and have a red and blue (3) or violet and green (3′) side. The molecular structures of 3, 3′ have been determined by single‐crystal X‐ray analyses. Both compounds contain two face‐joined octahedra, with two chloro and the NO ligands as bridges. The C‐nitroso groups together with the NC2 moiety of NMe2 (3) lie almost exactly within the symmetry plane of the molecules. Both the N atoms of 3 have a trigonal‐planar geometry. 3 and 3′ are the first single, neutral and dinuclear C‐nitroso complexes with the rare non‐assisted μ‐(η2‐N,O) bridge and only single atoms as additional bridges.
