Bis{2-ethoxy-6-[2-(methylammonio)ethyliminomethyl]phenolato}thiocyanatozinc(II) nitrate

In the title compound, [Zn(NCS)(C12H18N2O2)2]NO3, the ZnII ion is chelated by the phenolate O and imine N atoms from two zwitterionic Schiff base ligands and is also coordinated by the N atom of a thiocyanate ligand, giving a distorted trigonal-bipyramidal geometry. Intramolecular N—H⋯O hydrogen bonds are observed in the complex cation. The nitrate anions are linked to the complex cations through N—H⋯O hydrogen bonds.
