Lg. Lavrenova et al., COMPLEXES OF NICKEL(II) AND COPPER(II) CHLORIDES WITH A NITROXIDE RADICAL DERIVATIVE OF 4-TETRAZOLYL-3-IMIDAZOLINE-3-OXIDE, Russian chemical bulletin, 43(5), 1994, pp. 878-880
NiCl2 and CuCl2 complexes with a new stable nitroxyl radical, hyl-4-(t
etrazol-5-yl)-3-imidazoline-3-oxide-1-oxyl (L), NiLCl(2).H2O and CuLCl
(2), have been synthesized. The mu(eff) values attest to a weak exchan
ge interaction between the paramagnetic centers in the temperature int
erval of 78-300 K.
