The title complex, [Zn(NCS)(C(13)H(20)N(2)O(2))(2)]NO(3), consists of a complex mononuclear Zn(II) cation and a nitrate counter-anion. The Zn(II) ion is five-coordinate in a trigonal-bipyramidal geometry. The thio-cyanate 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.
标题配合物[Zn(NCS)(C₁₃H₂₀N₂O₂)₂]NO₃由一个单核Zn(II)阳离子配合物和一个硝酸根抗衡阴离子组成。Zn(II)离子呈三角双锥几何构型，为五配位。硫氰酸根的N原子以及来自两个席夫碱的两个O原子确定了赤道平面，来自相同两个席夫碱的两个亚胺N原子占据轴向位置，N-Zn-N键角为175.98 (7)°。席夫碱配体的胺N原子被质子化，不参与与金属的配位。两个取代苯环之间的二面角为87.7 (2)°。硝酸根抗衡离子通过N-H⋯O氢键与阳离子相连。
