(Benzoato-κ2 O,O′)(5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane-κ4 N,N′,N′′,N′′′)nickel(II) perchlorate monohydrate

The Ni atom in the title salt, [Ni(C7H5O2)(C16H36N4)]ClO4·H2O, is in a six-coordinate octahedral geometry. The metal atom is chelated by the carboxylate group, and the macrocyclic ligand adopts a folded configuration. The cation, anion and water molecules engage in hydrogen bonding to form a layer structure.
