Synthesis and magnetic properties of copper(II) (phenylsulphinyl)ethane complexes

Two Cu complexes, [Cu(-L)Cl·HO and Cu(-L)Cl [-L and -L = meso- and rac-PhS(O)(CH)S(O)Ph, respectively], were synthesized and characterized by elemental analysis, i.r. spectra and molar conductances. In each case, the Cu ion bonds to the 557-01 moiety through oxygen, and may be bridged by the ligand (-L or -L). From magnetic moment measurements at room temperature and variable temperature magnetic susceptibilities, we suggest that complexes and exhibit weak ferromagnetic behaviour.
