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

The title complex, [Zn(NCS)(C13H20N2O2)2]NO3, consists of a complex mononuclear ZnII cation and a nitrate counter-anion. The ZnII ion is five-coordinate in a trigonal-bipyramidal geometry. The thiocyanate N atom and two O atoms from two Schiff bases define the equatorial plane, and the two imine N atoms from the same two Schiff bases occupy the axial positions, with an N—Zn—N angle of 175.98 (7)°. The amine N atoms of the Schiff base ligands are protonated and are not involved in the coordination to the metal. The dihedral angle between the two substituted benzene rings is 87.7 (2)°. The nitrate counter-ions are linked to the cations through N—H...O hydrogen bonds.
