Intermolecular hydrogen bonding between the water molecules coordinated to the Na+ ion of 2 and the DMF molecules and intramolecular hydrogen bonding between a water molecule coordinated to the Na+ ion and a phenolate oxygen atom of the metallacrown. For clarity the hydrogen bonding has been divided into three sections (a), (b) and (c), only the hydrogen atoms (white) involved in the hydrogen bonding have been included, and only the atoms involved in the hydrogen bonding have been labeled. See Fig. 1 for additional display details. |
