The left-handed hydrogen-bonded helical chains formed between the coordinated water molecules and the uncoordinated carboxylate O atoms within the triangular interstices. The helical axes are represented by the long bars. [Symmetry codes: (i) x, y, z + 1; (iii) −y + 1, x − y, z + ; (iv) −x + y + 1, −x + 2, z + .] |
