Crystal structure of 2-hydroxy-N-(2-hydroxyethyl)-N-{2-hydroxy-3-[(E)-N-hydroxyethanimidoyl]-5-methylbenzyl}ethanaminium acetate monohydrate

The structure of the title hydrated mol­ecular salt, C(14)H(23)N(2)O(4) (+)·C(2)H(3)O(2) (−)·H(2)O, was determined as part of a wider study on the use of the mol­ecule as a polydentate ligand in the synthesis of Mn(III) clusters with magnetic properties. The cation features intra­molecular O—H⋯N and N—H⋯O hydrogen-bond inter­actions. The crystal structure features a range of inter­molecular hydrogen-bonding inter­actions, principally O—H⋯O inter­actions between all three species in the asymmetric unit. An R (2) (4)(8) graph-set hydrogen-bonding motif between the anion and water mol­ecules serves as a unit which links to the cation via the di­ethano­lamine group. Each O atom of the acetate anion accepts two hydrogen bonds.
