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-κ⁴N³,N⁷,O²⁵,O²⁶:κ⁴N¹⁵,N¹⁹,O²⁵,O²⁶]dicopper(II) bis­(perchlorate)

In the dinuclear title complex, [Cu₂(C₃₀H₃₈N₄O₂)(H₂O)₂](ClO₄)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 N₂O₃ 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 S₄ 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.

{6,6′-Dimeth­oxy-2,2′-[cyclo­hexane-1,2-diylbis(nitrilo­methanylyl­idene)]diphenolato}copper(II) monohydrate

In the title compound, [Cu(C₂₂H₂₄N₂O₄)]·H₂O, the Cu^II atom is four-coordinated in a distorted planar geometry with a mean deviation of 0.1164 (2) Å for the plane generated by the ligating atoms of the salen-type Schiff base ligand. In the crystal, O(water)—H...O and C—H...O hydrogen bonds form a three-dimensional-network.
