Structural twisting by $\sim$32° between the semiquinoneiminecopper(II) entities in I caused by weak Cu-S interaction results in a different spin arrangement ($\uparrow$,$\downarrow$,$\uparrow$) than for a planar deriv. without the thioether group ($\uparrow$,$\uparrow$,$\downarrow$). Most revealingly, I has an EPR spectrum typical for a radical whereas the non-thioether analog is known to display a signal for a CuII center. Oxidn. state distributions for the I 2+,+,0,-,2- forms are assigned from UV/visible/NIR spectroelectrochem. on SciFinder(R)
