Abstract top

In the title complex, [Fe(C11H10N5O4)(CH3O)(C5H5N)]·CH4O, the FeIII ion has a distorted pentagonal-bipyramidal geometry. In the crystal structure, molecules are linked into one-dimensional chains along [1\overline{1}\overline{1}] via intermolecular O-H...O and N-H...O hydrogen bonds.

Comment top

Metal-hydrazide complexes, especially Fe complexes with acetylhydrazide, continue to attract considerable attention due to their biological activities and structural versatilities (Drozdzewski et al., 2006; Sreeja et al., 2004) We report herein, the crystal structure of the title complex. A view of the title complex (I) is shown in Fig.1. The FeIII ion has a distorted pentagonal-bipyramidal coordination geometry, formed by one 2-oxido-N, N'-2,6-picoloylhydrazide ligand, one pyridine ligand and one methanol molecule. The distances involving atom Fe1 atom are consistent with those in a Fe complex with pentagonal-bipyramidal coordination geometry (Bonardi et al., 1991). Both intermolecular O—H···O and N—H···O hydrogen bonding occur in the crystal structure (Table 2).

Experimental top

A pyridine solution (10 mL) of N,N'-diacetyl-2,6-picoloylhydrazide (0.2 mmol,0.0559 g) was mixed with a methanol solution (10 mL) of iron chloride (0.2 mmol, 0.0808 g). The mixture was stirred at room temperature for 6 h and then filtered. Dark block-shaped crystals of the title complex suitable for X-ray diffraction analysis were obtained after three weeks (m.p. >573 K). Elemental analysis calculated for (C18H23N6O6)Fe: C 45.49, H 4.88, N 17.68%; found: C 45.41, H 4.76, N 17.50%.

Refinement top

All H atoms were placed geometrically and treated as riding on their parent atoms, with pyridine C—H distances of 0.93 Å, methyl C—H distances of 0.96 Å, methanol hydroxyl O—H distances of 0.82 Å, hydrazide N—H distances of 0.86Å and Uiso(H)=1.2Ueq(C,N) or 1.5Ueq(O).

Special details top

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.
