title: 2,2',2'',2'''-[Pyridine-2,6-diylbis(methyl-ene-nitrilo)]tetra-ethanol.
abstract: In the crystal structure of the title compound C(15)H(27)N(3)O(4), the mol-ecule is located on a twofold axis and the asymmetric unit contains one half-mol-ecule, with one N and one C atom lying on the rotation axis. The pyridine ring is the hydrogen-bond acceptor, while two hydroxyl O atoms act as hydrogen-bond donors in intra-molecular O-H⋯N and intermolecular O-H⋯N and O-H⋯O hydrogen bonds, thereby forming a closed hydrogen-bonded cage.
