  Spin-State Crossover with Structural Changes in a Cobalt(II) Organometallic Species: Low-Coordinate, First Row, Heteroleptic Amido Transition Metal Aryls. Synthesis and Characterization of Ar′MN(H)Ar^# (M = Mn, Fe, Co) (Ar′ = C₆H₃-2,6-(C₆H₃-2,6-ⁱPr₂)₂, Ar^# = C₆H₃-2,6-(C₆H₂-2,4,6-Me₃)₂)

  摘要：

  The synthesis and characterization of the monomeric aryl transition metal amido complexes Ar'MN(H)Ar-# (Ar' = C6H3-2,6-(C6H3-2,6-Pr-i(2))(2), Ar-# = C6H3-2,6-(C6H2-2,4,6-Me-3)(2), M = Mn (1), Fe (2), Co(3a, b)) are reported. The compounds were characterized by X-ray crystallography, electronic and infrared spectroscopy, and magnetic measurements. At about 90 K the complexes 1 and 2 possess quasi-two coordinate geometry with a weak, secondary, M-C interaction involving a flanking aryl ring from an amido group, In contrast, at the same temperature, their cobalt analogue 3a features a strong Co-eta(6)-flanking ring interaction to give an effectively higher coordination geometry. Magnetic studies of 1-3a showed that I and 2 have high spin configurations, whereas the cobalt species 3a has a low-spin configuration (S = 1/2). However, 3a undergoes a spin crossover to a high spin (S = 3/2) state 3b near 229 K. An X-ray structural determination above the crossover temperature at 240 K showed that the low temperature structure of 3a had changed to 3b which involves a weak secondary M-C interaction analogous to those in 1 and 2. The complexes 1-3 are very rare examples of heteroleptic quasi-two coordinate open shell transition metal complexes.
