Several complexes of the type (diamine)2Cu2(CO)(02CR)+X -, which contain both a carbonyl and a carboxylate group bridging two coppers, have been prepared. The preferred method of synthesis involves the reaction of T1(02CR) and (diamine)CuI under a CO atmosphere. All the complexes are characterized by a CO absorption in the infrared at approximately 1900-1950 cm-1. A related compound, (tmed)2Cu2(CO)C4O4, which contains a bridging squarate group, was also prepared and the structure of its CH2C12 solvate characterized by single-crystal X-ray diffraction. The geometry of the squarate complex is quite similar to that of the benzoate derivative in spite of the charge difference and the much larger "bite" of the squarate ligand compared to the benzoate group.
