✦ Synopsis

Two/l-phenoxo-bridged binuclear copper(II) complexes, [FsaI(GG)2Cu2C13].H20 (I) containing an exogenous chloride-bridge and FsaI(GG)zCu2(OH)z-H20

(2) containing an exogenous hydroxide-bridge, where {Fsal(GG)z = 2,6-bis[N-(acetylglycine)-imino-methylene]-4-methylphenol}, were synthesized. The complexes were characterized be several spectroscopic methods. According to variable temperature magnctic susceptibility measurements (4-300 K), the hydroxide-bridged complex (2) has a weak antiferromagnetic spin exchange integral (J = -23.6 cm), while the chloride complex (I) has an unusual weak ferromagnetic spin exchange integral (J = + 30.9 cm); both complexes have similar optical spectra in the aqueous solutions.
