Copper and Bismuth Complexes Containing Dipyridyl gem-Diolato Ligands: Bi2III[(2-Py)2CO(OH)]2(O 2CCF3)4(THF)2, CuII[(2-Py)2CO(OH)]2(HO2CCH 3)2,

The reactions of the singly deprotonated di-2-pyridylmethanediol ligand (dpmdH^-) with copper(II) and bismuthfill) have been investigated. A new dinuclear bismuth(III) complex Bi2(dpmdH)2(O2CCF3) 4(THF)2, 1, has been obtained by the reaction of BiPh3 with di-2-pyridyl ketone in the presence of HO2CCF3 in tetrahydrofuran (THF). The reaction of Cu(OCH3)2 with di-2-pyridyl ketone, H2O, and acetic acid in a 1:2:2:2 ratio yielded a mononuclear …
