(5,5,7,12,12,14-Hexamethyl-1,4,8,11-tetra­azacyclo­tetra­decane-1,8-diacetato)nickel(II) tetra­hydrate

The Ni atom in the title compound, [Ni(C₂₀H₃₈N₄O₄)]·4H₂O, is chelated by four N atoms of the macrocycle and also covalently bonded to two carboxyl­ate groups, in a cis-N₄O₂Ni octa­hedral environment. The mononuclear complex inter­acts with the solvent water mol­ecules to form a three-dimensional network structure.
