(Received 24 September 2009; accepted 29 September 2009; online 3 October 2009)

In the title compound, [PdBr2(C10H8N2)]·CH2Cl2, the Pd2+ ion is four-coordinated in a slightly distorted square-planar environment by two N atoms of the chelating 2,2′-bipyridine ligand and two bromide ions. The compound displays intra­molecular C—H⋯Br hydrogen bonds and pairs of complex mol­ecules are assembled by inter­molecular C—H⋯Br hydrogen bonds. These pairs are connected by additional C—H⋯Br hydrogen bonds, forming a layer structure extending parallel to (011). Inter­molecular π–π inter­actions between the pyridine rings of the ligand are also present, the shortest centroid–centroid distance being 4.090 (9) Å.

Comment top

The asymmetric unit of the title compound, [PdBr2(C10H8N2)].CH2Cl2, contains a neutral PdII complex and a solvent molecule (Fig. 1). The compound crystallizes in the triclinic space group P1, whereas the previously reported solvent-free complex [PdBr2(C10H8N2)] crystallizes in the monoclinic space group C2/c (Smeets et al., 1997).

In the title complex, the Pd2+ ion is four-coordinated in a slightly distorted square-planar environment by two N atoms of the 2,2'-bipyridine (bipy) ligand and two Br anions. The main contribution to the distortion is the tight N1—Pd1—N2 chelate angle (80.6 (5)°), which results in a non-linear trans arrangement (<N1—Pd1—Br1 = 175.7 (3)° and <N2—Pd1—Br2 = 175.7 (4)°). Each of the two Pd1—N and Pd1—Br bond lengths are almost equal, (Pd1—N: 2.042 (9) and 2.051 (11) Å; Pd1—Br 2.4182 (18) and 2.4044 (19) Å), and close to those reported for [PdBr2(C10H8N2)] (Smeets et al., 1997). The compound displays inter- and intramolecular C—H···Br hydrogen bonds (Table 1). Pairs of complex molecules are assembled by intermolecular hydrogen bonds, and the dichloromethane solvent molecules connect the pairs by intermolecular hydrogen bonds, thereby forming a layer structure extending parallel to (011) (Fig. 2). There may also be intermolecular π-π interactions between adjacent pyridine rings of the lignad (the symmetry operation for second plane is -x,-y,-z), with a shortest centroid-centroid distance of 4.090 (9) Å, and the planes are parallel and shifted for 1.758 Å.

Experimental top

To a solution of K2PdBr4 (0.100 g, 0.198 mmol) in EtOH (10 ml) was added 2,2'-bipyridine (0.031 g, 0.198 mmol), and refluxed for 4 h. The precipitate obtained was separated by filtration and washed with EtOH and water and dried under vacuum to give an orange powder (0.054 g). Crystals suitable for X-ray analysis were obtained by slow evaporation from a CH2Cl2 solution.

Refinement top

H atoms were positioned geometrically and allowed to ride on their respective parent atoms [C—H = 0.95 (CH) or 0.99 (CH2) Å and Uiso(H) = 1.2Ueq(C)]. The highest peak and the deepest hole in the final Fourier map are 1.30 Å from atom Pd1 and 0.81 Å from the same 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.
