O hydrogen bonds, which link the molecules into a chain parallel to the b axis.
N hydrogen bonds into linear chains. N hydrogen-bond interactions are present, resulting in a one-dimensional supramolecular chain structure.
Each conformer resides on a centre of inversion. Disordered C atoms in the ring bearing the carbonyl group of the matrinium cation cause the ring to appear in half-chair and half-boat conformations. In the crystal structure, two of the molecules form a hydrogen-bonded dimer, while the third forms a centrosymmetric hydrogen-bonded dimer with its symmetry-equivalent molecule. The bond lengths are normal.
O hydrogen bonds, generating two edge-fused motifs, viz.

Both intra- and intermolecular hydrogen bonds are present between the hydroxyl groups, resulting in a one-dimensional hydrogen-bonding network. O hydrogen bonds, which link the molecules into a chain parallel to the b axis.
The molecule is approximately planar for all non-H atoms. O contacts in the structure. Apart from the hydroxy group, the molecule is essentially planar.

The hydroxy, amino and carbonyl groups are all involved in hydrogen bonding. The hydroxy, amino and carbonyl groups are all involved in hydrogen bonding.
An intramolecular hydrogen bond occurs between the oxazole and hydroxy groups. The tetrahydrofuran and dihydrodiazepine rings adopt envelope conformations.
The data reveal that some strain is probably present in the bicyclic structure.
