Diaqua­[μ-11,23-di-tert-butyl-3,7,15,19-tetra­azatricyclo­[19.3.1.1(9,13)]tetra­cosa-1(25),2,6,9,11,13(26),14,19,21,23-do­decaene-25,26-diolato-κ(4) N (3),N (7),O (25),O (26):κ(4) N (15),N (19),O (25),O (26)]dicopper(II) bis­(perchlorate)

In the dinuclear title complex, [Cu(2)(C(30)H(38)N(4)O(2))(H(2)O)(2)](ClO(4))(2), the coordination cation has crystallographically imposed twofold rotational symmetry. The Cu(II) ion is five-coordinated by two N and two O atoms from the macrocylic ligand and one O atom from a water mol­ecule, forming a square-pyramidal N(2)O(3) geometry with the water mol­ecule in the apical position. The distance between the two Cu(II) atoms is 3.0930 (5) Å. Hydrogen bonds between water mol­ecules and between water mol­ecules and perchlorate anions assemble two cations and four anions into discrete supermolecules of S (4) symmetry. Intramolecular O—H⋯N hydrogen bonds are also observed. The perchlorate anion and the tert-butyl group are disordered over two positions, with occupancies of the major positions of 0.527 (11) and 0.592 (9), respectively.
