title: (Tris{2-[(5-hy-droxy-pyridin-2-yl-κN)methyl-idene-imino-κN]eth-yl}amine)-zinc dinitrate.
abstract: In the complex cation of the title compound, [Zn(C(24)H(27)N(7)O(3))](NO(3))(2), the tripodal tris-{[2-(5-hy-droxy-pyridin-2-yl)methyl-idene-imino]-eth-yl}amine ligand is coordin-ated to the Zn atom through the three pyridine and three imino N atoms. The coordination sphere of the Zn atom is based on an octahedron with a significant distortion towards trigonal prismatic, the twist angle being 45.58 (9)°. The crystal packing is formed by L and D anti-podes arranged in layers disposed parallel to the b axis. Strong O-H⋯O hydrogen bonding exists between the hy-droxy groups of the ligand and the nitrate anion.
