N,N,N′,N′-Tetra­kis(2-hy­droxy-5-methyl­benz­yl)ethane-1,2-diamine dimethyl­formamide disolvate

The title compound, C(34)H(40)N(2)O(4)·2C(3)H(7)NO, was synthesized by the Mannich condensation of ethane­diamine, formaldehyde and p-cresol. In the crystal, the tetra­phenol mol­ecule is arranged around an inversion center. The mol­ecule and the dimethyl­formamide solvate are linked through an O—H⋯O hydrogen bond. An intra­molecular O—H⋯N hydrogen bond occurs in the tetra­phenol mol­ecule, which may influence the mol­ecular confomation. Futhermore, C—H⋯O and π–π stacking inter­actions [centroid–centroid distance = 3.7081 (14) Å] stabilize the crystal packing, building a three-dimensional network.
