title: 4,4'-Bipyridine-2,2'-(1,2-phenylene-dioxy)diacetic acid-water (1/1/1).
abstract: In the title 1:1:1 adduct, C(10)H(8)N(2)·C(10)H(10)O(6)·H(2)O, the dihedral angle between the rings of the 4,4-bipyridine molecule is 10.981 (8)°. In the crystal, O-H⋯O and O-H⋯N hydrogen bonds link the mol-ecules into a zigzag chain structure.
