  Charge-Transfer Salts of Octamethylferrocenyl Thioethers and [M(mnt)₂]^- Complexes (M = Ni, Co, Pt). Synthesis, Structure, and Physical Properties

  摘要：

  The new ferrocene derivatives Fe(eta(5)-C5Me4SR)(2) (R = Me, 4: R = t-Bu, 5) have been prepared from the corresponding cyclepentadiene and FeCl2. 5 may be converted to the bis(thiobenzoate) 6, a protected form of dithiol 8. From 6 the octamethyl trithiaferrocenophane 9 may be obtained in good yields. Compounds 4 and 5 are easily oxidized and form paramagnetic salts containing [M(mnt)2](-) anions (M = Co, Ni, Pt). The derivatives [Fe(eta(5)-C5Me4SMe)(2)] [Ni(mnt)(2)], 14, [Fe(eta(5)-C5Me4SMe)(2)] [Pt(mnt)(2)], 15, [Fe(eta(5)-C5Me4SMe)(2)] [Co(mnt)(2)], 16, [Fe-(eta(5)-C(5)Me(4)St-Bu)(2)] [Ni(mnt)(2)], 17, [Fe(eta(5)-C(5)Me(4)St-Bu)(2)] [Pt(mnt)(2)], 18, and [Fe(eta(5)-C(5)Me(4)St-Bu)(2)] [Co(mnt)(2)], 19, have been prepared and fully characterized. X-ray crystal structural studies of 14 and 16-19 have been carried out. 14 and 16 display stacks of strongly interacting [M(mnt)(2)](-) anions, whereas 19 contains discrete [Co(mnt)(2)] dimers. 17 and 18 are isomorphous and display a typical D(+)A(-)D(+)A(-) structural motif. SQUID susceptibility measurements indicate a weak ferromagnetic ordering at low temperature for these two compounds.

  Charge-transfer salts of branched-alkyl biferrocenes, (1', 1"'-R-2-1,1"-biferrocene)[Ni(mnt)(2)] (1a, R = isopropyl; 2a, R = dineopentyl) and (1', 1"'-R2-1,1"-biferrocene)(2)[Co(mnt)(2)](2) (1b, R = isopropyl; 2b, R = dineopentyl), were prepared. Their valence states were investigated using X-ray crystallography and Mossbauer spectroscopy. Complexes 1a and 1b show segregated-stack crystal structures that contain columns of acceptors, whereas structures of 2a and 2b, which contain bulky donors, are rather discrete. All of the complexes contain mixed-valent biferrocenium monocations. A two-step valence transition was found in complex 1a. The crystal contains two crystal log raphically independent cations: one undergoes valence localization below room temperature; the other undergoes valence localization below ca. 130 K. The former transition is derived from asymmetry of the crystal environment around the cation, whereas the latter one is caused by symmetry lowering coupled with a spin-Peierls transition (T-C = 133.2 K) associated with the dimerization of the acceptors. This compound was found to exhibit a dielectric response based on valence tautomerization. Other complexes (1b, 2a, and 2b) show a valence-trapped state. In all complexes, charge localization was found to occur through local electrostatic interactions between the donor's cationic moiety and the acceptor's electronegative moieties.
