Bis[-2-{bis(2-pyridylethyl)amino}phenolato]bis[aquanickel(II)] dinitrate tetrahydrate

U. Pal Chaudhuri, B. Varghese and N. N. Murthy

Abstract: The title complex, [Ni₂(L-O^-)(H₂O)₂](NO₃)₂·4H₂O, where L-O^- is bis{2-[bis(2-pyridyl)ethyl]amino}phenol (C₂₀H₂₀N₃O), is dimeric with each Ni²⁺ ion coordinated by two bridging phenolate O atoms and three N atoms of the N₃O-tetradentate ligand anion L-O^-. A molecule of water on each metal completes the octahedral geometry. Crystallographic inversion symmetry is present at the center of the Ni₂O₂ plane of the dimeric unit.
