Abstract
Two heterometallic chain coordination polymers with the chemical formula {[Cu 2Mn 2L 2(CH 3OH)(H 2O)] · 0.5CH 3OH · 0.5CH 3CH 2OH} n ( 1) and {[Cu 2Co 2L 2(H 2O) 2] · H 2O} n ( 2) have been synthesized and characterized by IR, UV spectroscopy and single-crystal X-ray structural analysis, where H 4L = 2-hydroxy-3-[(E)-({2-[(2-hydroxybenzoyl)amino]ethyl}imino)methyl] benzoic acid. Magnetic measurements showed that the two compounds exhibit antiferromagnetic coupling exchange interactions, and satisfactory fittings to the observed magnetic susceptibility data were obtained by assuming a linear four-spin arrangement with two isotropic magnetic exchange interactions.
