Abstract
The title compound, C22H30N4O2, has a crystallographic inversion center located at the mid-point of the N—N single bond. Apart from the four ethyl C atoms, the non-H atoms are nearly coplanar with a mean deviation of 0.0596 (2) Å. An intramolecular O—H⋯N hydrogen bond occurs. In the crystal, weak intermolecular C—H⋯O hydrogen bonds link the molecules into layers parallel to (100).
