The structure of the title compound, [Cu(C₁₄H₉NO₄)(C₁₂H₈N₂)]_n, consists of zigzag polymeric chains along the c axis. The asymmetric unit contains one Cu^II atom which is coordinated by one 2,2′-iminodibenzoate ligand and a one phenanthroline unit. Two intramolecular N—H

O hydrogen bonds occur. The supramolecular structure is characterized by weak C—H

O hydrogen bonds and π–π stacking interactions, forming a three-dimensional supramolecular network. The shortest centroid–centroid distances between neighbouring phenanthroline aromatic rings and 2,2′-iminodibenzoate rings are 3.684 (1) and 3.640 Å, respectively. The shortest intrachain Cu

Cu distance is 7.2885 (9) and the shortest Cu

Cu distance between Cu atoms in different chains is 7.1103 (6) Å.

Comment top

This work is part of a project of synthesizing low dimensional polynuclear magnetic materials with Copper(II) and oxygen-donors bridging ligands (Fabelo et al., 2009; Martins et al., 2008a; Martins et al., 2008b; Silva et al., 2001; Yuste et al., 2007, 2008).

The target of this work is the use of an aromatic dicarboxylic acid, such as the 2,2'-iminodibenzoic acid, (H₂IDC) and another quelate, known as ''coligand'' that will block some coordination positions of the Copper(II) metal ion, modulating the dimensionality of the resulting compound. (Gao et al., 2009; Lin et al., 2006; Yuste et al., 2008).

The structure of this compound consists of neutral chains of formula [Cu(C₁₄H₉NO₄)(C₁₂H₈N₂)]_n, growing along the c-axis, in a zigzag mode, where the 2,2'-iminodibenzoate (IDC^2-) units act as linkers between two Cu(II) ions, in a bis-bidentate mode, and the phenanthroline molecules are placed out-of-chain. The whole compound adopts a three dimensional supramolecular structure by weak π-π stacking. The shortest intra- and interchain copper···copper distances are 7.2885 (9) Å [Cu1···Cu1ⁱ; (i) = x, 1 - y, -1/2 + z] and 7.1103 (6) Å [Cu1···Cu1^v; (v) = 1/2 - x, 1/2 - y, 1 - z], respectively.

The Copper(II) ion shows a distorted octahedral environment, CuN₂O₄, due to the Jahn-Teller effect. The equatorial positions are occupied by the two nitrogen atoms from the phenanthroline ligand, [N1 and N2], and two oxygen atoms [O1 and O4], from two different carboxylate units of the IDC^2- ligand, varying the distances in a very narrow range of [1.940–2.026 Å]. Another two oxygen atoms [O2 and O3], with bond length values 2.618 (2) and 2.438 (3) Å respectively, are placed in the axial positions. The 2,2'-iminodibenzoate links two neighboring Copper(II) metal ions, being the bite angle 55.19 (11)° [O1—Cu1—O2] and 58.92 (11)° [O3—Cu1ⁱⁱ—O4]. [(ii) = x, -y, -1/2 + z]. The ligand is not planar, with a maximum deviation of 1.472 (5) Å for C10 from the mean plane, being the dihedral angle between the two aromatic rings 52.25 (3)°, which is greater than those already reported (Field et al., 2002; Gao et al., 2009).

Intramolecular hydrogen bond interactions exist inside the 2,2'-iminodibenzoate unit between the nitrogen atom [N1] from the amino group and two oxygen atoms [O2 and O3] from the carboxylate groups. The intermolecular π-π stacking interaction exists in between two aromatic rings of two neighbor phenantrolines and also between the aromatic rings of two neighbor 2,2'-iminodibenzoate moieties. These weak π-π interactions, stabilize the crystal structure of the complex. The shortest distances 'centroid-to-centroid' between neighbor aromatic ring of two phenantrolines and two neighbor 2,2'-iminodibenzoate are 3.684 (1) and 3.640 Å respectively.

Experimental top

All the reagents, phenanthroline, 2,2'-Iminodibenzoic acid, and the metallic salt Cu(NO₃)₂.3H₂O, were purchased from commercial sources and used as received with no further purifications.

An aqueous solution containing Cu(NO₃)₂.3H₂O (1 mmol, 0.0242 g), Iminodibenzoic acid (1 mmol, 0.0257 g) and phenanthroline, ((2 mmol, 0.0361 g), was stirred during 30 minutes and placed in a 25 mL Teflon-lined autoclave and then heated at 120°C during 48 h. Dark green crystals were obtained by filtration, washed with water and dried in air. Ca. 36% yield based on Cu.

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.
