The 2(C11H9N)2], contains one half of a neutral PdII complex, with the complete molecule generated by the application of a twofold rotation axis; the N—Pd—N atoms lie on the axis. The PdII ion has a trans-Cl2N2 square-planar coordination geometry defined by two N atoms from two 4-phenylpyridine ligands and two Cl− anions. In the the pyridine ring and the phenyl ring were found to be disordered over two sites with the site-occupancy factors being 0.53 (2) and 0.51 (1), respectively, for the major components.

To a solution of Na2PdCl4 (0.2942 g, 1.000 mmol) in H2O (20 ml) and EtOH (10 ml) was added 4-phenylpyridine (0.3111 g, 2.005 mmol), followed by stirring for 3 h at room temperature. The formed precipitate was separated by filtration, washed with H2O and EtOH, and dried at 50 °C, to give a pale-yellow powder (0.4650 g). Crystals suitable for X-ray analysis were obtained by slow evaporation from its CH3CN solution.
H atoms were positioned geometrically and allowed to ride on their respective parent atoms [C—H = 0.95 Å and Uiso(H) = 1.2Ueq(C)]. One pyridyl ring (N1—C3) and one phenyl ring (C11—C14) displayed relatively large displacement factors so that the rings appear to be partially disordered. The C1, C2, C12 and C13 atoms were refined anisotropically as disordered over two sites, with the site-occupancy factors of 0.53 (2) and 0.51 (1) for the major components, respectively. The highest peak (1.25 e Å-3) and the deepest hole (-0.51 e Å-3) in the difference Fourier map are located 1.68 Å and 0.57 Å from the atoms H14 and Cl1, respectively.
The
of the title complex, [PdCl2(C11H9N)2], contains one half of a neutral PdII complex (Fig. 1). The complex is disposed about a twofold rotation axis running in the [010] direction passing through the Pd1, N1, C3, C4, C7, N2, C10, C11 and C14 atoms. The structure is similar to that of related PtII complex with a crystallization water, [PtCl2(C11H9N)2].H2O (Ha, 2011).In the complex, the central PdII ion has a trans-Cl2N2 square-planar coordination geometry defined by two N atoms from two distinct 4-phenylpyridine ligands and two Cl- anions. The two Pd—N bond lengths are nearly equal and the N—Pd—Cl bonds are almost perpendicular (Table 1). In the π-π interactions between the six-membered rings, with a shortest ring centroid-centroid distance of 4.511 (6) Å (Fig. 2).
one pyridine ring (N1—C3) and one benzene ring (C11—C14) were found to be disordered over two sites. The dihedral angles between the major and minor rings are 33.2 (12)° for the ring N1—C3 and 42.2 (6)° for the ring C11—C14. The molecules stack in columns along the a axis and display numerous intermolecularFor the

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. |

The asymmetric unit of the title complex, [PdCl2(C11H9N)2], contains one half of a neutral PdII complex (Fig. 1). The complex is disposed about a twofold rotation axis running in the [010] direction passing through the Pd1, N1, C3, C4, C7, N2, C10, C11 and C14 atoms. The structure is similar to that of related PtII complex with a crystallization water, [PtCl2(C11H9N)2].H2O (Ha, 2011).
In the complex, the central PdII ion has a trans-Cl2N2 square-planar coordination geometry defined by two N atoms from two distinct 4-phenylpyridine ligands and two Cl- anions. The two Pd—N bond lengths are nearly equal and the N—Pd—Cl bonds are almost perpendicular (Table 1). In the refinement, one pyridine ring (N1—C3) and one benzene ring (C11—C14) were found to be disordered over two sites. The dihedral angles between the major and minor rings are 33.2 (12)° for the ring N1—C3 and 42.2 (6)° for the ring C11—C14. The molecules stack in columns along the a axis and display numerous intermolecular π-π interactions between the six-membered rings, with a shortest ring centroid-centroid distance of 4.511 (6) Å (Fig. 2).
