In the title compound, C22H18N8·H2O, the dihedral angle between the tetrazole rings is 69.58 (1)° while the terminal phenyl ring makes dihedral angles of 26.98 (8) and 39.75 (8)° with the other benzene rings. The rings of the biphenyl unit subtend a dihedral angle of 55.23 (8)°. In the crystal, the solvent water molecule is linked to the main molecule via an N—H
O hydrogen bond. In addition, C—HN and O—HN hydrogen bonds link the components into chains along [010]. The crystal structure also features C—Hπ and π–π interactions, with centroid–centroid distances of 3.6556 (9) and 3.826 (1) Å.

In the title compound, C11H9NO3, the phenyl and isoxazole rings form a dihedral angle of 56.64 (8)°. The carboxy group is almost in the same plane as the isoxazole ring with a C—C—C—O torsion angle of −3.3 (2)°. In the crystal, pairs of O—HO hydrogen bonds link the molecules into head-to-head dimers. C—HN hydrogen bonds and π–π stacking interactions between phenyl rings [centroid–centroid distance = 3.9614 (17)Å] link the dimers into a three-dimensional network.
