Hydrogen-Bond-Based Magnetic Exchange Between mu-Diethylnicotinamide(aqua)bis(X-salicylato)copper(II) Polymeric Chains
Original language description
Polymeric salicylatocopper(II) complexes of unusual composition [Cu(X-sal)(2)(mu-denia)(H(2)O)](n) [denia = diethylnicotinamide, and X-sal = 5-methylsalicylate (1), 3-methylsalicylate (2), 4-methoxysalicylate (3), 3,5-dichlorosalicylate (4) and 3,5-dibromosalicylate (5)] were synthesized and characterized. Magnetic measurements were performed in the temperature range 1.8-300 K. The structural unit of all complexes consists of a Cu(II) atom, which is monodentately coordinated by the pair of X-salicylateanions in trans positions. Water and the diethylnicotinamide ligand occupy the other two basal plane positions of the tetragonal pyramid. The axial positions are occupied by a diethylnicotinamide oxygen atom of neighboring structural units, thus forminga spiral polymeric structure parallel to b axis. Magnetic measurements showed that all complexes 1-5 exhibit a susceptibility maximum at about 6-8 K. The obtained data fit to Bleaney-Bowers equation gave singlet-triplet energy gaps 2J = -
