Synthesis, molecular and supramolecular structures, electrochemistry and magnetic properties of two macrocyclic dicopper(II) complexes: Microporous supramolecular assembly

Synthesis, molecular and supramolecular structures, electrochemistry and magnetic properties of two diphenoxo-bridged dicopper(II) compounds [CuII2L(H2O)(ClO4)]·ClO4·2H2O (1) and [CuII2L(N3)2]·2H2O (2) derived from a tetraimino diphenolate macrocyclic ligand H2L, obtained on [2+2] condensation of 4-methyl-2,6-diformylphenol and 2,2′-dimethyl-1,3-diaminopropane, are presented. Interestingly, compounds 1 and 2 exhibit butterfly-like structure and 3-D microporous self-assembly, respectively.
