Di-μ-hydroxido-bis­{[bis­(6-methyl-2-pyridylmeth­yl)(2-phenyl­ethyl)amine-κ³N′,N′′,N′′′]copper(II)} bis(perchlorate)

The title compund, [Cu₂(OH)₂(C₂₂H₂₅N₃)₂](ClO₄)₂, is a copper(II) dimer, with two [CuL]²⁺ units [L is bis­(6-methyl-2-pyridylmethyl)­(2-phenyl­ethyl)amine] bridged by hydroxide groups to define the {[CuL](μ-OH)₂[CuL]}²⁺ cation. Charge balance is provided by perchlorate counter-anions. The cation has a crystallographic inversion centre halfway between the Cu^II ions, which are separated by 3.0161 (8) Å. The central core of the cation is an almost regular Cu₂O₂ parallelogram of sides 1.931 (2) and 1.935 (2) Å, with a Cu—O—Cu angle of 102.55 (11)°. The coordination geometry around each Cu^II centre can be best described as a square-based pyramid, with three N atoms from L ligands and two hydr­oxide O atoms completing the coordination environment. Each cationic unit is hydrogen bonded to two perchlorate anions by means of hydroxide–perchlorate O—H...O inter­actions.
