  Bistability and Molecular Switching for Semiquinone and Catechol Complexes of Cobalt. Studies on Redox Isomerism for the Bis(pyridine) Ether Series Co(py₂X)(3,6-DBQ)₂, X = O, S, Se, and Te

  摘要：

  Intramolecular electron transfer between Co-II(SQ) and Co-III(Cat) species has been investigated for the series of complexes Co(py(2)X)(3,6-DBQ)(2), where 3,6-DBQ are semiquinonate and catecholate forms of 3,6-di-tert-butyl-1,2-benzoquinone and py(2)X is bis(pyridine) ether and its heteroatomic analogs with X = S, Se, and Te. Transition temperature for Co(III)/Co(II) redox isomerism decreases in steps of approximately 30 K in toluene solution and in steps of 80 K in the solid state for the complexes with X = S, Se, Te. This appears to be primarily associated with an entropy increase that results from low-energy shifts in vibrational modes with increasing heteroatomic mass. Complexes containing py(2)O have been isolated at room temperature in two charge distributions, Co-II-(py(2)O)(3,6-DBSQ)(2) and Co-III(py(2)O)(3,6-DBSQ)(3,6-DBCat). Crystallographic characterization on both forms of the complex [Co-II(py(2)O)(3,6-DBSQ)(2), monoclinic, P2(1)/c, a = 11.0280(2) Angstrom, b = 30.2750(9) Angstrom, c = 12.1120(2) Angstrom, beta = 113.490(2)degrees, V = 3708.7(1) Angstrom(3), Z = 4, R = 0.056; Co-III(py(2)O)(3,6-DBSQ)(3,6-DBCat), monoclinic, P2(1)/n, a = 9.882(3) Angstrom, b = 20.915(5) Angstrom, c = 17.579(4) Angstrom, beta = 91.57(2)degrees, V = 3632(2) Angstrom(3), Z = 4, R = 0.054] has shown the the py(2)O ligand adopts a planar structure for the Co(II) isomer that shifts to a folded, nonplanar structure with the smaller Co(III) ion. This structural change is responsible for hysteresis in the Co(III) --> Co(II) and electron transfer steps in the solid state. Optically induced shifts in charge distribution have been investigated using a low-energy polychromatic light source.

  compound 3, the coordination of the soft tellurium donor atom to the soft copper(I) metal center was also observed. Compound [Cu(2-Py2TeClO-κO,N,N′)Cl]2 (4) was formed using bis(2-pyridyl)ditellane as a precursor. After the generation of bis(2-pyridyl)tellane (2-PyTePy-2) in situ, CuCl2·2H2O was added in DMSO. During the reaction, the tellurium atom was oxidized from +2 to +4, with the formation of the anionic
