In the title compound, C27H27N7O9·CH3CN, the three nitro groups of the polydentate tripodal Schiff base are located approximately parallel to their respective carrier benzene rings, making dihedral angles of 3.9 (4), 5.0 (4) and 6.3 (4)°. Intramolecular O—H⋯N hydrogen bonds between the hydroxy O atoms and the imine N atoms, with O⋯N distances in the range 2.607 (3)–2.665 (3) Å, form nearly planar six-membered rings. In the crystal, weak intermolecular C—H⋯O and C—H⋯N hydrogen bonds occur and several intra- and intermolecular π–π interactions are present between adjacent benzene rings, with a shortest centroid–centroid distance of 3.507 (2) Å.

Tris(2-aminoethyl)amine (0.7305 g, 4.995 mmol) and 5-nitrosalicylaldehyde (2.5077 g, 15.005 mmol) in EtOH (30 ml) were stirred for 3 h at room temperature. The precipitate was then separated by filtration, washed with ether, and dried at 50 °C, to give a yellow powder (2.9135 g). Crystals suitable for X-ray analysis were obtained by slow evaporation from a CH3CN solution.
H atoms were positioned geometrically and allowed to ride on their respective parent atoms [C—H = 0.95 Å (CH), 0.99 Å (CH2) or 0.98 Å (CH3) and O—H = 0.84 Å, and Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C, O)].
The title compound, C27H27N7O9.CH3CN, consists of a polydentate tripodal Schiff base and an acetonitrile solvent molecule (Fig. 1). The Schiff base can act as a tribasic hexa- or heptadentate ligand, that is, the N3O3 or N4O3 donor atoms can coordinate to a metal ion or metal ions. In the ═C) = 1.291 (4)–1.307 (4) Å and d(N—C) = 1.460 (4)–1.469 (4) Å; <C—N—C = 122.7 (3)–123.9 (3)°]. The compound displays strong intramolecular O—H···N hydrogen bonds between the hydroxy O atoms and the imine N atoms with d(O···N) = 2.607 (3)–2.665 (3) Å thus forming a nearly planar six-membered ring (Fig. 2, Table 1). There are also weak intermolecular C—H···O and C—H···N hydrogen bonds with d(C···O) = 3.290 (4)–3.359 (4) Å and d(C···N) = 3.360 (5)–3.369 (5) Å. Moreover, several intra- and intermolecular π–π interactions between the adjacent benzene rings are present, with a shortest ring centroid-centroid distance of 3.507 (2) Å, and the dihedral angle between the ring planes is 5.1 (2)°.
the Schiff base reveals an approximate threefold axis, when viewed down the apical amine N atom (N1) through the plane formed by the atoms C1, C10 and C19, and three nitro groups are located approximately parallel to their respective carrier benzene rings. The N—C bond lengths and the C—N—C bond angles indicate that the apical N1 atom is sp3-hybridized [d(N1—C) = 1.470 (4)–1.480 (4) Å; <C—N1—C = 109.5 (2)–111.7 (2)°] and the other imine N atoms (N2, N4, N6) are sp2-hybridized [d(NFor the

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. |

The title compound, C27H27N7O9.CH3CN, consists of a polydentate tripodal Schiff base and an acetonitrile solvent molecule (Fig. 1). The Schiff base can act as a tribasic hexa- or heptadentate ligand, that is, the N3O3 or N4O3 donor atoms can coordinate to a metal ion or metal ions. In the crystal structure, the Schiff base reveals an approximate threefold axis, when viewed down the apical amine N atom (N1) through the plane formed by the atoms C1, C10 and C19, and three nitro groups are located approximately parallel to their respective carrier benzene rings. The N—C bond lengths and the C—N—C bond angles indicate that the apical N1 atom is sp3-hybridized [d(N1—C) = 1.470 (4)–1.480 (4) Å; <C—N1—C = 109.5 (2)–111.7 (2)°] and the other imine N atoms (N2, N4, N6) are sp2-hybridized [d(N═C) = 1.291 (4)–1.307 (4) Å and d(N—C) = 1.460 (4)–1.469 (4) Å; <C—N—C = 122.7 (3)–123.9 (3)°]. The compound displays strong intramolecular O—H···N hydrogen bonds between the hydroxy O atoms and the imine N atoms with d(O···N) = 2.607 (3)–2.665 (3) Å thus forming a nearly planar six-membered ring (Fig. 2, Table 1). There are also weak intermolecular C—H···O and C—H···N hydrogen bonds with d(C···O) = 3.290 (4)–3.359 (4) Å and d(C···N) = 3.360 (5)–3.369 (5) Å. Moreover, several intra- and intermolecular π–π interactions between the adjacent benzene rings are present, with a shortest ring centroid-centroid distance of 3.507 (2) Å, and the dihedral angle between the ring planes is 5.1 (2)°.
