(Acetylacetonato-[kappa]2O,O')aqua[salicylaldehyde nicotinoylhydrazonato(2-)-[kappa]3O,N,O']manganese(III)

Abstract top

The MnIII atom in the title complex, [Mn(C13H9N3O2)(C5H7O2)(H2O)], is coordinated by three donors from a dianionic ligand, salicylaldehyde nicotylhydrazone, two O atoms from an acetylacetonate anion and a water molecule in a distorted octahedral geometry. There is an extended two-dimensional supramolecular motif resulting from O-H...N hydrogen bonds between the coordinated water molecule and a hydrazine N or pyridine N atom, and from C-H...O hydrogen bonds between a CH group and the phenolate O atom.

Comment top

Metal-organic supramolecular complexes with various fascinating topologies have been studied widely for their versatile chemical and physical properties and potential applications as functional materials (Janiak, 2003; Kitagawa et al., 2004). Self-assembly based on molecular building blocks has become an effective approach to construct these functional materials. In the development of supramolecular chemistry, hydrogen-bonding plays an important role in selfassembling multi-dimensional metal-organic supramolecular frameworks or networks (Graham & Pike, 2000). Some nicotylhydrazone derivatives and aroylhydrazone derivatives had led to a number of complexes with multidimensional structures or extended multidimensional structures. (Niu et al., 2005; Adams et al., 2000; Ranford et al., 1998). The syntheses and characterization of these complexes has been an area of rapid growth in recent years.(Batten & Robson, 1998; Hagrman et al., 1999). Herein, we report the synthesis and crystal structure of the title manganese(III) complex.

Complex (I) crystallizes in the space group P21/c. The crystal structure reveals that complex (I) consists of a neutral Mn(C13H9N3O2)(C5H7O2)(H2O) unit. As shown in Fig. 1, compound (I) is composed of one salicylaldehyde-nicotylhydrazone dianion, one acetylacetone anion, one coordinated water molecule and one MnIII cations. The manganese(III) atom exists in a distorted octahedral environment defined by one carbonyl oxygen atom O1, one hydrazine nitrogen atom N3 and one phenolate oxygen atom O2 of the deprotonated Schiff base ligand, the two oxygen atoms (O3 and O4) of the acetylacetonate (acac) anion and one oxygen atom O5 of the coordinated water molecule. O1, N3, O2 and O4 atoms are located in the equatorial plane, while O3 and O5 occupy the axial positions. The bond length of Mn1—O1 (carbonyl oxygen) in complex (I) is 1.935 (2) Å, while the corresponding values in the similar known complexes are between 1.959 (2) and 1.971 (1)Å (Kessissoglou et al., 2002). The bond length of Mn1—O2(phenolic oxygen) in complex (I) is 1.886 (2) Å, while the corresponding values in the known complexes are between 1.844 (3) and 1.923 (3)Å (Sailaja et al., 2003; Zhang et al., 2001; Clérac et al., 2002) The bond length of Mn1—N3(hydrazone nitrogen) in complex (I) is 1.972 (2) Å, which is similar to the corresponding values 1.968 (4)–1.999 (7)Å of the known complexes (Mitra et al., 2006; Hoshino et al., 2003). The bond distance of axial Mn1—O3 (acac-) (2.122 (2) Å) is 0.20 Å longer than that of the equatorial Mn1—O4(acac-) (1.920 (1) Å), O3 and O4 being from the same acac- ligand. This typical Jahn-Teller elongation along the z axis of the manganese(III) ion was also observed in some manganese(III) compounds (Nakamura et al., 2001; Liu et al., 2001). The title complex molecules are linked by hydrogen bonds (Table 1) into a two-dimensional supramolecular network. As illustrated in Fig. 2, one complex molecule connected to two neighboring complex molecules via hydrogen bonds of O—H(H2O)···N(hydrazine) type and C—H···O(phenolate) type, resulting in an extended chain along the c axis. These hydrogen bonds are marked with green color in Fig. 2. A t the same time, the neighboring extended chains are combined by O—H(H2O)···N(pyridine) hydrogen bonds with pink color, forming an extended two-dimensional network.

Experimental top

A DMF solution of salicylaldehyde-nicotylhydrazone ligand (24 mg, 0.1 mmol) and a methanol solution of Mn(acac)3 (35 mg, 0.1 mmol) were mixed and stirred for 3 h. The resulting solution was then left for aerial evaporation at room temperature. Black block crystals of (I), suitable in size for single-crystal X-ray diffraction, appeared after two weeks.

Refinement top

Water H atoms and the H atom attached to C16 in acac- group were founded in a difference Fourier map, and then allowed to ride on the O and C16 atoms with Uiso=1.5Ueq(O) and Uiso=1.2Ueq(C), respectively. The other H atoms were placed in idealized positions and treated as riding with C—H = 0.93 Å, Uiso(H) = 1.2Ueq(C) for aromatic and 0.96 Å, Uiso(H) = 1.5Ueq(C) for CH3 atoms.

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.
