Figure S1 (a) Packing diagram of [CoCl2(NITmepy)] 1 viwed along crystallographic a
axis; and (b) closest intermolecular contacts of [CoCl2(NITmepy)] 1 in the
crystal (symmetry operation for the primed atoms: x+1, y, z; only Co, imino
nitroxide and pyridine moieties are shown for clarity).
Figure S2 Packing diagram of [CoCl2(IMmepy)] 2.
Figure S3 Solvent-dependence of (a) UV-vis absorption and (b) MCD spectra of 1 in a
mixture of dichloromethane and acetonitrile at room temperature [(a)
CH2Cl2:CH3CN = 10:0, 9:1, 8:2, 6:4, 4:6, 2:8 and 0:10; (b) CH2Cl2:CH3CN
= 10:0, 8:2, 5:5 and 0:10].
Figure S4 UV-vis-NIR absorption spectra of [CoCl2(NITmepy)] 1 in dichloromethane
(— — — ), CoCl2•6H2O in acetonitrile (- - - - -) and NITmepy in
dichloromethame (– • – • – ) at room temperature.
Figure S5 UV-vis-NIR absorption spectra of [CoCl2(IMmepy)] 2 in dichloromethane
(— — — ), CoCl2•6H2O in acetonitrile (- - - - -) and IMmepy in
dichloromethame (– • – • – ) at room temperature.
Figure S6 Temperature-dependence of the anisotropic magnetic properties for
complex 1Br in the form of (// or ) vs. T and (// or )•T vs. T. The //
denotes the molar magnetic susceptibility when the crystallographic a axis
parallels to the magnetic field, and the  does that when the a axis is
directed to the perpendicular magnetic field.
