Abstract:	Summary By inhibiting the copper(II) assisted TPT (TPT = 2,4,6-tris(2-pyridyl)-1,3,5-triazine) hydrolysis, monomeric and dimeric copper(II) complexes having as general formulae Cu(TPT)X, · nH₂O (X = Cl, Br, NCS, NCO or N₃) and [Cu(TPT)X]₂(PF₆)₂ · nH₂O (X = Cl, Br, NCS or N₃) have been synthesized and characterized by i.r., electronic and e.p.r. spectra, x-ray powder diffraction and analytical data. Spectroscopic results indicate five-coordinate geometry around the copper(II) ion, intermediate between trigonal-bipyramid and square-pyramid structures. The half-field absorption in the M_S = 2 region of powdered X-band e.p.r. spectra has been observed for the dimeric species.
