Abstract
The crystal structure of a trigonal planar copper(I) complex, [Cu-(3,5-Ph2PzH)3][Cl], is reported. In the title compound, one nitrogen atom from each pyrazole ligand is coordinated to the copper(I) ion and each N–H of the pyrazoles forms a hydrogen-bond with the chloride resulting in a trigonal planar geometry about the copper(I) ion. The complex crystallizes in the trigonal space group R $$\overline 3$$ with a = b = 13.031(1) A, c = 37.3187(9) A, α = β = 90o, γ = 120o , V = 5464.5(2) A3, Z = 6. A trigonal planar copper(I) complex with three pyrazole ligands is reported in which the hydrogens of the bound pyrazole ligands are hydrogen bonded with the chloride counter ion.
