Synthesis and characterization of dinuclear copper(II) complexes, [Cu2([20]-DCHDC)(La)2] (La = N3−, NCS− or S2O32−) with tetraazadiphenol macrocyclic ligand having cyclohexane rings
Graphical abstract
The dinuclear tetraazadiphenol macrocyclic copper(II) complexes [Cu2([20]-DCHDC)(La)2] (La = N3−, NCS− or S2O32−) are prepared by reacting [Cu2([20]-DCHDC)Cl2]∙H2O with an aqueous solution of NaN3, NaSCN, or Na2S2O3. The stable monoclinic crystals, [Cu2([20]-DCHDC)(N3)2]∙2CH3OH (III) suitable for X-ray crystallography are grown from complex II solution on slow evaporation of solvent methanol.

Such difference of bond distances between 4 and 1–3 are usual in similar macrocyclic systems with three carbon atoms (as in 4) and two carbon atoms (as in 1–3) between the two imine nitrogen atoms [13,14,38,39]. In comparison to the four basal bond lengths, the apical bond distances are as usual significantly longer, 2.522 (in 1), 2.680 (in 2), 2.387(4) (in 3) and 2.1904(14) Å (in 4).

The basal plane is defined by two phenoxide oxygen atoms (Zn–O 1.995(2) Å) and two amine nitrogen atoms (Zn–N 2.087(3) and 2.121(3) Å) [10]. The mean deviation of the basal atoms from their least-square plane is 0.544(3) Å.
