In this paper we report on the synthesis and the crystallographic characterization of η3-1,3,5-triazacyclohexane (R3TAC) complexes of copper(I) and copper(II).The complexes 2> (1), (2), Cu(PPh3)>(BF4) (3), and (BF4) (4) were characterized by X-ray crystallography.The highly strained and bent Cu-N bonds are longer than in the corresponding complexes of other amine ligands.One methylene carbon atom of the ring comes close to the copper atom (2.55 - 2.65 Angstroem).However, investigation of the ring deuterated complexes by IR and X-ray crystallography (6>2) showed no clear evidence for attractive C-H-Cu interactions. - Keywords: Triazacyclohexanes; Copper complexes; Triphenylphosphane
