Diaqua-[?-11,23-di-tert-butyl-3,7,15,19-tetra-azatricyclo-[19.3.1.1(9,13)]tetra-cosa-1(25),2,6,9,11,13(26),14,19,21,23-do-decaene-25,26-diolato-?(4)N(3),N(7),O(25),O(26):?(4)N(15),N(19),O(25),O(26)]dicopper(II) bis-(perchlorate).

ABSTRACT: 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 mol-ecule, forming a square-pyramidal N(2)O(3) geometry with the water mol-ecule in the apical position. The distance between the two Cu(II) atoms is 3.0930?(5)?Å. Hydrogen bonds between water mol-ecules and between water mol-ecules 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.
