The addition of pyridine-3-carboxylic acid (3-PyCOOH), (E)-3-(pyridin-3-yl)acrylic acid (3-PyCH=CHCOOH), or 3-(pyridin-4-yl)benzoic acid (3-PyPhCOOH) to the Lewis acidic [Cu(dppf)(NCMe)(2)][BF4]center dot 2MeCN center dot 2H(2)O [1 center dot 2MeCN center dot 2H(2)O, dppf = 1,1-bis(diphenylphosphanyl)ferrocene] in the presence of NEt3 afforded the complexes [Cu-2(dppf)(2)(3-PyCOO)(2)]center dot 3CHCl(3) (2 center dot 3CHCl(3)), [Cu-2(dppf)(2)(3-PyCH=CHCOO)(2)]center dot CH2Cl2 center dot C6H14 (3 center dot CH2Cl2 center dot C6H14), and [Cu-2(dppf)(2)(3-PyPhCOO)(2)]center dot CH2Cl2 (4 center dot CH2Cl2) with a common metallomacrocycle core and doubly bridging pyridine-carboxylate ligands as spacers. These dinuclear complexes have been structurally characterized by single-crystal X-ray crystallography, and their emission activities have been studied.
