In the title complex, [Pd(C7H3NO4)(C13H9N)], the PdII ion is four-coordinated in a distorted square-planar environment by one N and two O atoms from the tridentate pyridine-2,6-dicarboxyl­ate (dipic) anionic ligand and one N atom of the acridine (acr) ligand. The dipic and acr ligands are nearly planar [maximum deviation = 0.069 (3) Å in dipic and 0.091 (4) Å in acr] and the dihedral angle between their mean planes is 58.67 (7)°. The Pd—O bond lengths are nearly equal, but the Pd—N bond lengths are slightly different. There is a short C—H⋯O inter­action in the mol­ecule involving the two ligands. In the crystal, complex mol­ecules are linked through C—H⋯O inter­actions, forming a three-dimensional network. There are also a number of inter­molecular π–π inter­actions present, the shortest ring centroid–centroid distance being 3.622 (3) Å.

Comment top

The title complex is isomorphous with the previously reported analogous PtII complex [Pt(dipic)(acr)] (Ha, 2011).

In the title complex, the PdII ion is four-coordinated in a distorted square-planar environment by one N and two O atoms from the tridentate pyridine-2,6-dicarboxylate (dipic) anionic ligand and one N atom of the acridine (acr) ligand (Fig. 1). The main contribution to the distortion is the tight N—Pd—O chelate angles [N1—Pd1—O1 = 81.25 (14)° and N1—Pd1—O3 = 81.17 (14)°], which results in a non-linear trans arrangement of the O1—Pd1—O3 bond with 162.40 (12)°, whereas the N1—Pd1—N2 bond is almost linear, 178.40 (16)°. The Pd—O bond lengths are nearly equal [2.036 (3) Å and 2.037 (3) Å], but the Pd—N bond lengths are slightly different. The Pd1—N1(dipic) bond [1.923 (4) Å] is somewhat shorter than the Pd1—N2(acr) bond [2.063 (4) Å] (Table 1). The dipic and acr ligands are nearly planar [maximum deviation = 0.069 (3) Å in dipic and 0.091 (4) Å in acr] and the dihedral angle between the least-squares planes of the two ligands is 58.67 (7)°. In the molecule, there is a short C19—H19···O3 interaction involving the two ligands.

In the crystal, complex molecules are linked through C—H···O interactions, forming a three-dimensional network (Fig. 2 and Table 2). The crystal structure also displays numerous intermolecular π···π interactions between adjacent six-membered rings: Cg1···Cg1i 3.822 (3) Å; Cg2···Cg2ii 3.622 (3) Å; Cg2···Cg2iii 3.854 (3) Å; Cg2···Cg3iii 3.638 (3) Å; Cg3···Cg4iii 3.986 (3) Å [Cg1, Cg2, Cg3 and Cg4 are the centroids of rings N1/C1-C5, N2/C8/C13-C15/C20, C8-C13 and C15-C20, respectively; symmetry codes: (i) x+1/2, -y+3/2, z+3/2; (ii) -x, y, -z+1/2; (iii) -x, -y+1, -z+1].

Experimental top

To a solution of acridine (0.0898 g, 0.501 mmol) in EtOH (20 ml) and MeOH (10 ml) were added pyridine-2,6-dicarboxylic acid (0.0838 g, 0.501 mmol) and Na2PdCl4 (0.1465 g, 0.498 mmol) and stirred for 3 h at room temperature. After addition of H2O (10 ml) to the reaction mixture, the formed precipitate was separated by filtration, washed with EtOH and ether, and dried at 333 K, to give a yellow powder (0.1546 g). Block-like yellow crystals, suitable for X-ray analysis, were obtained by slow evaporation of an acetone solution.

Refinement top

H atoms were positioned geometrically and allowed to ride on their respective parent atoms: C—H = 0.95 Å with Uiso(H) = 1.2Ueq(C). The highest peak (1.21 e Å-3) and the deepest hole (-1.14 e Å-3) in the difference Fourier map are located 1.38 Å and 0.99 Å, respectively, from the Pd1 atom.

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.
