摘要：

Reaction of the [N,N-diethyl,N'-ethylene(salicylideniminato)](salicylato) copper(II) complex [Cu(SalNEt2)(Sal)] with squaric acid in CH3OH affords [Cu2(SalNEt2)2(H2O)(C4O4)] . H2O, whose X-ray structure shows the first example of a binuclear copper(II) complex with an unusual mu-1,2-coordination mode for the bridging squarato (C4O42-) ligand. This type of linking leads to the shortest bimetallic distance, as well as to the largest antiferromagnetic interaction observed so far for squarato bridged copper(II) complexes.
