Abstract :
The crystal structure of the title compound, [Ni(C13H11N2O2)(H2O)4]Br3·2H2O, contains an octahedral NiII atom coordinated to the enol form of 1,3-dipyridylpropane-1,3-dione (dppo) and four water molecules. Both pyridyl rings on the ligand are protonated, forming pyridinium rings and creating an overall ligand charge of +1. The protonated nitrogen-containing rings are involved in hydrogen-bonding interactions with neighoring bromide anions. There are many additional hydrogen-bonding interactions involving coordinated water molecules on the NiII atom, bromide anions and hydration water molecules.
