Complexes containing di(2-pyridyl) ketone (dpk) as a bi- (N,N) and tridentate (N,N,O) ligand have been synthesised1,2 and characterized by spectral and structural studies. Products 1 and 2 are polymorphs of the polymeric copper(I) complex [Cu(dpk)(NCS)] containing dpk with thiocyanate anions which bridge to form a one-dimensional continuous polymer chain. The novel dinuclear copper(II) complex [Cu (dpk·acetone) (NCS) ] (3) was formed when 1 and 2 were allowed to stand in the supernatant. In this instance it appears that a transition-metal- promoted aldol condensation has occurred between the solvent acetone and the ketone carbonyl of dpk to produce the novel ligand, dpk·acetone.
