(Received 1 April 2010; accepted 8 April 2010; online 14 April 2010)

The ligand N-(2-hydr­oxy-3-methoxy­benzyl­idene)glycylglycine (H3L), a Schiff base derived from glycylglycine and 3-methoxy­salicylaldehyde, was used in the synthesis of a new organic–inorganic coordination complex, [Mn(H2O)6][Cu(C12H11N2O5)]2·6H2O. The MnII atom is located on an inversion center and is coordinated to six water mol­ecules in a slightly distorted octa­hedral geometry. The CuII atom is chelated by the tetra­dentate Schiff base ligand in a distorted CuN2O2 square-planar coordination. In the crystal structure, the complex [Mn(H2O)6]2+ cations and the [CuL]− anions are arranged in columns parallel to the a axis and are held together by O—H⋯O hydrogen bonding. Additional hydrogen bonds of the same type further link the columns into a three-dimensional network.

Comment top

Transition metal complexes of salicylaldehyde-peptides and salicylaldehyde-amino acid Schiff-bases are non-enzymatic models for pyridoxal-amino acid systems, which are of considerable importance as key intermediates in many metabolic reactions of amino acids catalyzed by enzymes (Zabinski et al., 2001; Wetmore et al., 2001; Bkouche-Waksman et al.,1988). Considerable effort has been devoted to the preparation, structural characterization, appropriate spectroscopic and magnetic studies of Schiff-base complexes derived from salicylaldehyde and amino acids and reduced salicylidene amino acids (Ganguly et al., 2008), but little attention has been devoted to Schiff bases derived from simple peptides (Zou et al., 2003). Herein, we report the structure study of [Mn(H2O)6][Cu(C12H11N2O5)]2.6H2O (H3L= Schiff base derived from glycylglycine and 3-methoxy-salicylaldehyde, C12H14N2O5).

The asymmetric unit of structure (I) consist of one-half of a [Mn(H2O)6]2+ cation (completed by crystallographic inversion symmetry), one [CuL]- anion and three water molecules (Fig. 1 and Table 1). The coordination environment of the CuII atoms is approximately square-planar. The Schiff-base ligand is deprotonated, thus acting as a triple negatively charged tetradentate ONNO chelate. It coordinates to the CuII atom via one phenolic oxygen atom (O2), one deprotonated amide nitrogen atom (N2), one imino nitrogen atom (N1) and one carboxylate oxygen atom (O4). The two Cu—N bond distances are 1.905 (5) Å (Cu1—N1) and 1.887 (5) Å (Cu1—N2). The two Cu—O bonds are 1.979 (4) (Cu1—O4) and 1.873 (4) Å (Cu1—O2). The phenyl ring [C1—C6] and the chelate ring [C1, C6, C7, N1, O2, Cu1] are almost coplanar with a small dihedral angle of 0.6°. The MnII center is octahedrally coordinated by the O atoms of six water molecules with Mn—O bond lengths in the range of 2.161 (4)-2.212 (4) Å.

Complex (I) shows an interesting stacking structure. The anions and cations of the complex form well-separated columns (Fig. 2) stacked along [100], held together by hydrogen bonding of the type O—H···O. The anion stacking is characterised by [CuL]- columns arranged in a zig-zag manner. The shortest Cu···Cu separation within a [CuL]- chain is 4.447 Å and the closest Cu···Cu separation between anionic chains is 9.312 Å. Additional O—H···O hydrogen bonds between the coordinated water molecules and uncoordinated water molecules further link the columns into a three-dimension network (Fig. 2, Table 1).

Experimental top

The Schiff base was prepared through the condensation of glycylglycine and 3-methoxy-salicylaldehyde. Glycylglycine (10 mmol) was dissolved and refluxed in absolute methanol (40 ml) containing LiOH.H2O (10 mmol). After cooling to room temperature, a solution of 3-methoxy-salicylaldehyde (10 mmol) in absolute methanol was added slowly under stirring for 10 min. Then Cu(NO3)2 (10 mmol) was added to the HLLi solution and the resulting solution was adjusted to pH = 9-11 by 1.0 mol/L NaOH solution. After stirring at room temperature for 30 min, the volume was reduced to ca. 5 ml in vacuo. Anhydrous ethanol was added to precipitate the product, which then was recrystallized in methanol solution. Na[CuL].2H2O (2 mmol) was dissolved in 10 ml water. Then MnCl2.4H2O (1 mmol) was added to the solution under stirring. The resulting crude product was precipitated. It was recrystallized in hot water 363 K and filtered. The filtrate was allowed to evaporate slowly at room temperature. After several days red to violet crystals suitable for X-ray diffraction were obtained.

Refinement top

The water H atoms in the complex were located in a difference Fourier map and were refined with a distance restraint of O—H = 0.85 Å and Uiso(H) = 1.5Ueq(O). All other H atoms were positioned geometrically and were constrained as riding atoms, with C—H distances of 0.93–0.97 Å and Uiso(H) set to 1.2 or 1.5Ueq(C) of the parent atom.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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.
