catena-Poly[[[(2,2′-bipyridyl)copper(II)]-μ-L-alaninato] perchlorate monohydrate]

In the structure of the polymeric title complex, {[Cu(C₃H₆NO₂)(C₁₀H₈N₂)]ClO₄·H₂O}_n, the carboxylate group of the chelating amino acid is further linked to a neighbouring Cu centre, generating a supramolecular single-stranded chain parallel to [010]. The structure displays intermolecular N—H

O and O—H

O hydrogen bonding, which consolidates the crystal packing.

Comment top

The structure of the title complex, (I) and Fig. 1, is of interest with respect to the stereochemistry of the complexed aminoacid, the coordination geometry of the metal centre and the single-stranded supramolecular assembly created primarly by further coordination of the carboxylate group of the aminoacid, Fig. 2. The secondary association is by crosslinks realised through H-bonds between the created chains, Fig. 3. The supramolecular structure described for (I) is found in other (aminoacidato)(2,2'-bipyridyl)copper(II) complexes, such as in the tryptophanato (Masuda et al., 1991) and aspartato complexes (Antolini et al., 1983). The assembly has also been identified in the proline complex but not described as a supramolecular association (Sgarabotto et al., 1999). For the alaninate complex, see also Solans et al. (1992).

Experimental top

The synthesis of (I) was realized by using an intermediate complex, i.e. tris(2,2'-bipyridyl)copper(II), as shown in Fig. 4. The cation in (I) was prepared according to the following procedure: Two ethanolic solutions, one containing 2,2'-bipyridyl (0.31 g, 2 mmol/5 mL) and another containing Cu(ClO₄)₂.2H₂O (0.6 g, 2 mmol/5 mL) were mixed with stirring. To the resulting suspension of a blue powder, an alkaline solution of L-alanine (0.18 g alanine + 0.08 g NaOH 2 mmol/10 mL water) was added dropwise (see also Scheme 2). The suspension cleared and changed colour to dark-blue. The mixture was heated to 50°C and Na₂ClO₄ (1 mmol) was added. After 10 mins, the solution was cooled and filtered. The filtrate was allowed to stand at room temperature for several days when dark-blue crystals, suitable for X-ray analysis, separated, collected and washed with a methanolic solution.

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.
