Bis[[mu]2-N'-acetyl-2-hydroxy-6-oxidobenzohydrazidato(3-)]octapyridinetrinickel(II)

Abstract top

The title trinuclear complex, [Ni3(C9H7N2O4)2(C5H5N)8], possesses a crystallographically imposed center of symmetry occupied by one NiII ion. Each of the three NiII ions is coordinated by two O and four N atoms, respectively, in a distorted octahedral geometry. In the crystal, weak intermolecular C-H...[pi] interactions link the molecules into ribbons propagating in the [100] direction.

Comment top

In recent years, a large number of N-acetylsalicylhydrazide complexes have been prepared and studied due to their potential applications in chemically modified (Lin et al., 2002) and anion-selective separation agents (John et al., 2004). However, structures of nickel(II) complexes with N-acetyl-6-hydroxysalicylhydrzaide were not reported. So we have synthesized the title compound, which has been characterized by X-ray diffraction and elemental analysis.

The title complex (Fig. 1) contains three nickel(II) centers having distorted octahedral coordination environment, two ligand molecules and eight pyridine molecules. The triple-deprotonated N-acetyl-6-hydroxysalicylhydrzaide ligands bridge metal ions via hydrazide N—N group forming trinuclear nickel complex. In the crystal, the complex molecules are linked into ribbons via intermolecular C—H···π weak interactions (Table 1, Fig. 2).

Experimental top

A solution of Ni(OAc)2.4H2O (0.4 mmol, 0.0996 g) in dimethylformamide (10 ml) was add to N-acetyl-(6-hydroxysalicylhydrzaide) (0.2 mmol, 0.042 g) in pyridine (10 ml). A reddish solution was obtained after refluxing for 3 h. After the solution had been stanging for two weeks, red block crystals suitable for X-ray diffraction appear.(m.p. >400 K). Elemental analysis calculated for C58H54N12O8Ni3: C 56.95, H 4.45, N 13.74%; found: C 56.92, H 4.44, N 13.76%.

Refinement top

All H atoms were placed geometrically and treated as riding on their parent atoms with C—H 0.93 (pyridine, benzene) or 0.97 (methylene) Å [Uiso(H) = 1.2Ueq(C)], and O—H 0.82 Å (hydroxyl) [Uiso(H) = 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.
