4,4′,6,6′-Tetra-tert-butyl-2,2′-[1,2-phenylenebis(nitrilomethylidyne)]diphenol acetone solvate

Abstract

In the Schiff base mol­ecule of the title compound, C36H48N2O2·C3H6O, the central benzene ring makes dihedral angles of 46.64 (10) and 49.34 (10)° with the two outer benzene rings, and the two outer benzene rings form an angle of 39.13 (8)°. There are two intra­molecular O—H⋯N hydrogen bonds involving the two hydr­oxy groups, which generate S(6) ring motifs. In the crystal structure, the Schiff base mol­ecules are linked into a chain along the a axis by C—H⋯π inter­actions. The acetone solvent mol­ecules are attached to the chain via C—H⋯O hydrogen bonds.

“…They are also used as versatile ligands in coordination chemistry (Ali et al, 2008;Kargar et al, 2009;Yeap et al, 2009). Recently, the crystal structures of several Schiff base compounds have been reported (Fun et al, 2009;Nadeem et al, 2009;Eltayeb et al, 2008). In this paper, the new Schiff base title compound, (I), Fig.…”
