Whereas the central cation [Cu(msbi)(2)Cl](+) = 1(+) in [Cu(msbi)(2)Cl]Cl center dot 2MeOH crystallizes in an approximately mixed square-pyramidal/trigonal-bipyramidal structure (tau = 0.52) with the second and third row atoms chlorine and selenium in the equatorial plane, the related [Cu(msbi)(2)(MeOH)](BF4)(2) = [2](BF4)(2) exhibits a closer to square-pyramidal arrangement with tau = 0.36 for that complex dication 2(2+). In both cases, the Cu-N bonds are short at about 1.94 angstrom, whereas the Cu-Se distances vary between 2.62 angstrom for 1(+) and ca. 2.54 angstrom for 2(2+). Slight differences between the Jahn-Teller influenced species 1(+) and 2(2+) are also apparent from absorption and EPR spectra. Workplace J.
