摘要：
Novel copper(II) dimer complexes, [Cu-2{OCOC(6)H(3)Me-2-(NHCOBu(t))-6}(4)(MeOH)(H2O)] and [Cu-2{OCOC6H3(NHCOBu(t))(2)-2,6}(4)(MeCN)(2)], containing bulky, intramolecularly NH...O hydrogen-bonded carboxylate ligands; are synthesized; the former shows a distorted Cu-O-C-O-Cu structure with a magnetic exchange (-2J = 302 cm(-1)) between the two Cu-II ions while the latter has a twisted Cu-O-C-O-Cu structure with a relatively large exchange (-2J = 460 cm(-1))through the NH...O hydrogen bonds.
