Diaquadiperchlorato[μ-11,23-dimethyl-3,7,15,19-tetraazatricyclo[19.3.1.1^9,13]hexacosa-1(25),2,7,9,11,13(26),14,19,21,23-decaene-25,26-diolato-1κ²N,N′;2κ²N′′,N′′′;1:2κ²O:O′]dicadmium(II) diaqua[μ-11,23-dimethyl-3,7,15,19-tetraazatricyclo[19.3.1.1^9,13]hexacosa-1(25),2,7,9,11,13(26),14,19,21,23-decaene-25,26-diolato-1κ²N,N′;2κ²N′′,N′′′;1:2κ²O:O′]dicadmium(II) diperchlorate

In the title complex, [Cd₂(C₂₄H₂₆N₄O₂)(ClO₄)₂(H₂O)₂][Cd₂(C₂₄H₂₆N₄O₂)(H₂O)₂](ClO₄)₂, the two distinct macrocycles adopt essentially flat structures. They each encapsulate two Cd atoms. One Cd coordination polyhedron, completed by a water O atom and a perchlorate O atom, is distorted octa­hedral, while the other is best described as a CdN₂O₃ square-based pyramid, with water in the apical site. Both dinuclear complexes are centrosymmetric.

Bis­[μ-4-fluoro-6-hydroxymethyl-2-(2,5,8-triaza­oct-1-enyl)phenolato]dicopper(II) bis(perchlorate) methanol solvate

The title dinuclear complex, [Cu₂(C₁₂H₁₇FN₃O₂)₂](ClO₄)₂·CH₄O, was synthesized by condensation between diethyl­ene­triamine and 2-form­yl-4-fluoro-6-hydroxy­methyl­phenol in the presence of copper(II). It contains two similar units, which are linked by Cu—O bonds. The approximate planes of the two units are parallel to each other, and π–π inter­action exists between the two units.
