Diaquabis(3,7-dichloroquinoline-8-carboxylato)zinc(II) monohydrate

In the title compound, [Zn(C10H4Cl2NO2)2(H2O)2]·H2O, the Zn atom has a distorted square-pyramidal geometry comprising two O atoms and one N atom from two distinct 3,7-dichloroquinoline-8-carboxylate ligands, and two water molecules. The free water molecules are involved in intermolecular O—H...O hydrogen bonding with the coordinated water molecules and carboxylate O atoms, to give a one-dimensional helical chain along the [100] direction
