(4,4,12,12-Tetramethyl-5,8,11-triazapenta-2,14-dione 2-oxime 14-oximato-5N)copper(II) perchlorate: a copper(II) compound with a pentadentate triamine–oxime–oximate ligand
The title compound, [Cu(C16H34N5O2)]ClO4, has discrete square-pyramidal (triamine–oxime–oximato)copper(II) cations and perchlorate anions. The cations have very approximate mirror symmetry, with the oxime [Cu—N = 2.066 (2) Å], oximate [Cu—N = 2.087 (2) Å] and amine N atoms [Cu—N = 2.138 (2) and 2.095 (2) Å] in the tetrahedrally twisted basal plane, and the `central' amine N atom coordinated axially [Cu—N = 2.183 (2) Å]. The oxime and oximate groups are linked by an O—H…O hydrogen bond, forming a pseudo-cyclic pentadentate ligand, with an O…O distance of 2.395 (3) Å.
