Bis(9-aminoacridinium) bis(pyridine-2,6-dicarboxylato)cuprate(II) trihydrate

Z. Derikvand, J. Attar Gharamaleki and H. Stoeckli-Evans

The asymmetric unit of the title compound, (C₁₃H₁₁N₂)₂[Cu(C₇H₃NO₄)₂]·3H₂O, consists of one [Cu(pydc)₂]²⁻ dianion (pydc is pyridine-2,6-dicarboxylate), two 9-aminoacridinum monocations and three uncoordinated water molecules. The Cu^II atom is coordinated by two pydc dianions acting as tridentate ligands, and forming five-membered chelate rings with copper(II) as the central atom. The Cu^II atom is surrounded by four O atoms in the equatorial plane and two pyridine N atoms in axial positions, resulting in a distorted octahedral coordination geometry. In the crystal, there are two types of O—H

O and N—H

O hydrogen-bonding synthons linking the anionic and cationic fragments and the water molecules, namely R₄⁴(16), and R₄²(8). There are also weak C—H

O hydrogen bonds, π–π stacking interactions [the shortest centroid–centroid distance is 3.350 (2) Å], and a C—O

π interaction [O

centroid distance = 3.564 (2) Å], which connect the various components into a three-dimensional network.

Comment top

A number of complexes containing a copper(II) atom, pyridine-2,6-dicarboxlic acid and various bases have been reported (Yenikaya et al., 2009; Zafer Yeşilel et al., 2010; Du et al., 2006; Aghabozorg et al., 2006, 2009). Herein, we report on the crystal structure of the title compound, that consists of a discrete [Cu(pydc)₂]^2- dianion, two 9-aminoacridinum monocations and three uncoordinated water molecules (Fig. 1).

The copper(II) atom is coordinated by two pyridine-2,6-dicarboxylate anions (pydc) acting as tridentate ligands, forming five membered chelate rings. The metal center is surrounded by four oxygen atoms (O1, O3, O5 and O7) in the equatorial plane and by two pyridine nitrogen atoms (N1 and N2) in axial positions. In the anionic complex the N1—Cu1—N2 angle of 174.13 (8)° deviates significantly from linearity. The coordination geometry around the copper(II) atom is distorted octahedral (CuN₂O₄), and the valence angles vary considerabley from the required 90° and 180° in the basal plane i.e. 75.13 (8) - 159.50 (8) °. The (pydc)^2– ligands are almost orthogonal, with a dihedral angle involving the pyridine ring mean planes of 83.78 (13)°.

In the crystal two types of O–H···O and N–H···O hydrogen bond synthons are found namely, i [R⁴₄(16)], and ii [R²₄(8)] (Bernstein et al., 1995) [Table 1]. As shown in Fig. 2 they link the anionic and cationic fragments and the lattice water molecules to form a chain propagating in (110). Other intermolecular interactions are also present and include weak C–H···O hydrogen bonds, π–π stacking interactions [i-vii,ix in Fig. 3; the shortest centroid-to-centroid distance is 3.350 (2) Å], and a C–O···π interaction [viii in Fig. 3; O···centroid distance = 3.564 (2) Å], as shown in Fig. 3.

The crystal structure of the title compound is similar to that of (aacH)₂[Ni(pydc)₂]^. 3H₂O, (aacr = 9-aminoacridine) (Derikvand et al. 2010).

Experimental top

An aqueous solution of copper(II) nitrate hexahydrate (0.5 mmol, 145 mg) in distilled water (5 ml) was added to a methanolic solution of pyridine-2,6-dicarboxylic acid (1 mmol, 167 mg) in distilled water (20 ml) and 9-aminoacridine (1 mmol, 194 mg) in methanol (5 ml) under stirring at 353 K, in a 1:2:2 molar ratio. The pale-green precipitate produced was dissolved in H₂O/DMSO with the volume ratio of 1:4 (2/8 ml). Green plate-like crystals, suitable for X-ray characterization, were obtained after 3 days at room temperature.

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
