摘要：

The title compound Cu2(fsa)2en, CH3OH was synthesized and its crystal structure solved at room temperature from 3830 independent reflections. It crystallizes in the monoclinic system, space group P21/n. The lattice constants are a = 11.456(5) Å, b = 11.425(3) Å, c = 14.357(4) Å and β = 104.15(3)° with Z = 4. Least squares refinement of the structure led to a conventional weighted R factor of 0.043. The structure is made of non-symmetrical binuclear units in which a copper atom is five-fold coordinated to two nitrogens, two phenolic oxygens and an oxygen of the methanol molecule, the other copper atom being coordinated to two phenolic oxygens and two carboxylic oxygens in a plannar manner. The temperature dependence of the magnetic susceptibility, studied in the range 10-312 K, showed a strong antiferromagnetic coupling with a J singlet-triplet separation of -650 cm-1. This magnetic behaviour was compared to those of the other binuclear complexes with the same Cu2O2 network and an explanation for such a strong coupling was proposed. © 1979.
