Poly[tris{μ(2)-4-[4-(di-methyl-amino)-phenyl-diazenyl]benzene-sulfonato}tri-dioxane-tri-sodium(I)]

(2,6-Bis{5-amino-3-tert-butyl-4-[(3-methyl-1,2,4-thia-diazol-5-yl)diazen-yl]-1H-pyrazol-1-yl}-4-oxo-1,4-dihydro-1,3,5-triazin-1-ido)methanol(phenol)sodium phenol tetra-solvate

The title compound, [Na(C₂₃H₂₈N₁₇OS₂)(CH₃OH)(C₆H₅OH)]·4C₆H₅OH, is a five-coordinate Na^I complex. The Na⁺ cation is bound to three N atoms of the triazinide ligand, two from each pyrazole ring and one from the central deprotonated triazine ring system. O atoms from a methanol and a phenol mol­ecule complete the five-coordinate NaN₃O₂ coordination environment. The asymmetric unit also includes three complete and two half phenol mol­ecules, four of which are hydrogen bonded to the N atoms of the thia­diazole ring. Two of the phenol solvent mol­ecules are disordered over two discrete inversion centres. The triazinide ligand is essentially planar (mean deviation from the least-squares plane = 0.0524 Å), with the methyl groups of the tert-butyl substituents on the pyrazole rings located above and below the plane. The planarity of this system is further assisted by the formation of four intra­molecular N—H⋯N hydrogen bonds between the N—H bonds of both amino groups on the pyrazole rings and the N atoms of the triazine ring and also from each of the adjacent diazene (–N=N–) bonds. The highly polar mol­ecules are stacked along the a axis through the central Na atom sandwiched by two kinds of alternating inter­molecular hydrogen bonds: O(carbon­yl)⋯H—O(methanol)/Na/O—H(phenol)⋯O(carbon­yl). These inter­actions form two polymer chains per mol­ecule.
