6,6'-Dimeth­oxy-2,2'-{[(E,E)-hydrazine-1,2-diyl­idene]bis­(methanylyl­idene)}diphenol methanol disolvate

The title compound, C₁₆H₁₆N₂O₄·2CH₃OH, is a hydrazone in an E geometric arrangement, with an inversion centre at the mid-point of the N-N bond. A symmetry-related pair of six-membered hydrogen-bonded rings [graph-set motif S¹₁(6)] are present for the terminal vanillin-imine moieties. Two lattice methanol solvent mol­ecules are present per formula unit (Z' = 1/2), which form hydrogen-bonded chains along [010] with two orientations due to disorder of the methanol H-atom.

1,2-Bis{4-[1-(anthracen-9-ylmeth­yl)-1H-1,2,3-triazol-4-yl]phen­yl}-1,2-bis­[4,5-bis­(methyl­sulfan­yl)-1,3-dithiol-2-yl­idene]ethane

The title mol­ecule, C₅₈H₄₄N₆S₈, has point symmetry 2 (in the Schönfliess notation C₂). The related crystallographic twofold axis bis­ects the central ethane bond while it is parallel to the monoclinic unique axis of the unit cell. The dithiole=C—C=dithiole torsion angle is 103.7 (4)° and the triazole–anthracene moieties adopt a pincer-like conformation. The crystal structure features C—H...S and C—H...N contacts. The distance between the stacked anthracene fragments [centroid—centroid separations of 3.6871 (19) Å, off-set by 1.516 (3) Å and mean anthracene plane-plane separations of 3.361 (2) Å], which are parallel to (101) and (-101), indicates inter­molecular anthracene–anthracene π–π contacts. One of the terminal methyl­sulfanyl groups was modelled as being disordered with two refined orientations that converged to occupancies of 0.809 (5) and 0.191 (5).
