μ-(2,6-Bis{[3-(di­methyl­amino)­prop­yl]imino­meth­yl}-4-methyl­phenolato)-μ-hydroxido-bis­[(thio­cyanato-κN)copper(II)]

In the title compound, [Cu₂(C₁₉H₃₁N₄O)(OH)(NCS)₂], the mol­ecular structure of the dinuclear complex reveals two penta­coordinated Cu^II ions, which are bridged by the phenolate O atom of the ligand and by an exogenous hydroxide ion. The bridging atoms occupy equatorial positions in the coordination sphere of the metal atoms and complete the equatorial coordination planes with two ligand N atoms, the apical positions being occupied by thio­cyanate N atoms. The crystal structure also features π–π stacking inter­actions involving the benzene rings with a centroid–centroid distance of 3.764 (4)Å. The crystal studied was a non-merohedral twin, with a refined BASF value of 0.203 (2)

2,2′-{[(1E,1′E)-(Cyclo­hexane-1,4-diyl)­bis(aza­nylyl­idene)]bis­(ethan-1-yl-1-yl­idene)}diphenol

The title compound, C₂₂H₂₆N₂O₂, crystallizes with three independent mol­ecules, two of which are situated on inversion centers, so the asymmetric unit contains two independent half-mol­ecules and one mol­ecule in a general position. The two hy­droxy groups in each mol­ecule are involved in intra­molecular O—H...N hydrogen bonds, which generate S(6) rings. In the crystal, weak inter­molecular C—H...π inter­actions link the mol­ecules into two crystallographically independent columns propagating along [001]; one column consists of mol­ecules in general positions, while the other column is built from alternating independent centrosymmetric mol­ecules.
