چکیده
In the structure of the title compound, C(37)H(40)N(4)O(8), penta-erythrityltetra-mine is bonded to four o-vanillin mol-ecules, forming a four-armed Schiff base mol-ecule. These mol-ecules are connected by inter-molecular C-H⋯O hydrogen bonds. Intramolecular C-H⋯N and O-H⋯N hydrogen bonds are also present.
