In the complex cation of the title compound, [Zn(C24H27N7O3)](NO3)2, the tripodal tris{[2-(5-hydroxypyridin-2-yl)methylideneimino]ethyl}amine ligand is coordinated 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 antipodes arranged in layers disposed parallel to the b axis. Strong O—H⋯O hydrogen bonding exists between the hydroxy groups of the ligand and the nitrate anion.

To a stirred boiling mixture of 5-hydroxy-picolinaldehyde (Seredyuk et al., 2008) (0.5 g, 0.406 mmol) and Zn(NO3)2.6H2O (0.403 g, 0.136 mmol) in ethanol was added tris(2-aminoethyl)amine (0.198 g, 0.136 mmol). The obtained mixture was kept boiling for 15 min and then transferred into a fridge and left at 4°C overnight. The crystalline precipitate was filtered off, washed with a small portion of cold ethanol and air dried. Recrystallization in a thermostat from boiling methanol provided colorless crystalline material. ESI MS (rel. int.): m/z 587 [M+NO3]+ (17%), 524 [M–H]+ (100%) 264 [M]++ (18%). Calc for C24H27N9O9Zn: C, 44.28, H, 4.18, N, 19.37. Found C, 44.20, H, 4.28, N, 19.27.
The OH hydrogen atoms were located from the difference Fourier map, and their positional and thermal parameters were refined freely. The CH hydrogen atoms were positioned geometrically and refined as riding atoms, with C–H = 0.95–0.99 Å and with Uiso = 1.2 Ueq(parent atom).
As a part of our study of the tripodand-based 3d-metal complexes (Seredyuk et al., 2007; Seredyuk et al., 2008; Seredyuk et al., 2011), we report the
of the title compound.The tripod ligand tris[2-(5-hydroxy-2-pyridylmethyleneimino)ethyl]amine coordinates to the metal centre through the three pyridine and three imino N atoms (Fig. 1). The
of the zinc ion in the complex molecule is a distorted trigonal antiprism with the twist angle equal to 46.71 (8)°. The tertiary capping N1 atom lies on the pseudo C3–axis of the molecule and is situated at 2.972 (2) Å from the Zn center. The average values for the Zn–Npy and the Zn–Nim bond lengths differ significantly and are 2.265 (2) and 2.132 (2) Å, respectively. Similar differences in the geometrical parameters have been observed before in the related zinc complexes (Petrusenko et al.,1997; Świątek-Kozłowska et al., 2000; Wörl et al., 2005). The C—C and C—N bond lengths in the pyridine rings are normal for 2-substituted pyridine derivatives (Krämer & Fritsky, 2000; Sachse et al., 2008; Moroz et al., 2010).The crystal packing is formed by L and D antipodes arranged in layers disposed parallel to the b axis (Fig. 2). A strong hydrogen bonding is settled between hydroxy groups of the ligand and nitrate anions [2.593 (3)–2.698 (3) Å].

Experimental. The OH hydrogen atoms were located from the difference Fourier map, and their positional and thermal parameters were refined freely. The CH hydrogen atoms were positioned geometrically and refined as riding atoms, with C—H = 0.95 - 0.99 Å and with Uĩso~ = 1.2 U~eq~(parent atom). |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

As a part of our study of the tripodand-based 3d-metal complexes (Seredyuk et al., 2007; Seredyuk et al., 2008; Seredyuk et al., 2011), we report the crystal structure of the title compound.
The tripod ligand tris[2-(5-hydroxy-2-pyridylmethyleneimino)ethyl]amine coordinates to the metal centre through the three pyridine and three imino N atoms (Fig. 1). The coordination polyhedron of the zinc ion in the complex molecule is a distorted trigonal antiprism with the twist angle equal to 46.71 (8)°. The tertiary capping N1 atom lies on the pseudo C3–axis of the molecule and is situated at 2.972 (2) Å from the Zn center. The average values for the Zn–Npy and the Zn–Nim bond lengths differ significantly and are 2.265 (2) and 2.132 (2) Å, respectively. Similar differences in the geometrical parameters have been observed before in the related zinc complexes (Petrusenko et al.,1997; Świątek-Kozłowska et al., 2000; Wörl et al., 2005). The C—C and C—N bond lengths in the pyridine rings are normal for 2-substituted pyridine derivatives (Krämer & Fritsky, 2000; Sachse et al., 2008; Moroz et al., 2010).
The crystal packing is formed by L and D antipodes arranged in layers disposed parallel to the b axis (Fig. 2). A strong hydrogen bonding is settled between hydroxy groups of the ligand and nitrate anions [2.593 (3)–2.698 (3) Å].
