Abstract

In the title coordination polymer, {[Zn(C11H15O3)2(C10H8N2)(C11H16O3)]·H2O}n, the ZnII ion is five coordinated by two N atoms from two 4,4′-bipyridine (4,4′-bpy) molecules and three O atoms from two 3-hydroxyadamantane-1-carboxylate anions (L) and one 3-hydroxyadamantane-1-carboxylic acid (HL) molecule. The resulting coordination polyhedron is a near regular ZnN2O3 trigonal bipyramid, with the N atoms in axial sites. The 4,4′-bpy molecules [dihedral angle between the aromatic rings = 17.2 (2)°] act as bridges, connecting the metal ions into an infinite polymeric chain propagating in [-101]. O—H...O hydrogen bonds help to consolidate the packing.
