The crystal structure of the complexes [Cu(sac)2(bzim)2(H2O)] (1) and [Cu(sac)2(bzim)(H2O)(EtOH)] · 2 EtOH (2) (sac = saccharinate anion; bzim = benzimidazole; EtOH = ethanol) was determined by single crystal X-ray diffractometry. Complex 1 crystallizes in the monoclinic C2/c space group with Z = 8 whereas complex 2 belongs to the triclinic P1 space group with Z = 2. Room temperature magnetic susceptibilities as well as electronic and IR spectra of both complexes were discussed. Their thermal behaviour was investigated by means of TG and DTA methods.
