The NiII ions are in slightly distorted coordination environments. In the crystal structure, intermolecular O¡ªH...O and weak C¡ªH...O hydrogen bonds link cations and water molecules into a three-dimensional network. One of the three uncoordinated water molecules is half-occupied. %U http://scripts.iucr.org/cgi-bin/paper?S1600536808034806
