Abstract: The mononuclear copper(II) complexes [CuL(ClO4)(H2O)2]ClO4 and [CuL(bipy)(ClO4)]ClO4 [L = 2,2,4,4,6,6-hexakis(3,5-dimethylpyrazolyl)-2λ5,4λ 5,6λ5-cyclotriphosphaza-1,3,5-triene] have been prepared and characterized by optical, EPR and IR spectral data. The crystal structure of an unusual cyclophosphazene-bridged dicopper complex [H2dmpz][(CuCl2)2{N3P 3O(dmpz)5}] (Hdmpz = 3,5-dimethylpyrazole) has been determined: space group P1, a = 11.640(3), b = 14.497(14), c = 14.775(3), α = 77.62(6), β = 82.10(2), γ = 74.88(6)°, and Z = 2. The geometry around both copper atoms is a distorted trigonal bipyramidal with the axial positions occupied by pyrazolyl pyridinic nitrogens and the equatorial positions by one cyclophosphazene ring nitrogen and two chlorine atoms.
