Source of material

The title compound was obtained from the reaction of 2-(4-bromophenyl)pyridine and [RuCl2(p-cymene)]2 according to literature procedures [3] and recrystallized from a dichloromethane/petroleum ether solution at room temperature to give the desired crystals suitable for single-crystal X-ray diffraction.

Experimental details

A suitable crystal was selected and measured on a Xcalibur, Eos, Gemini diffractometer. The diffraction data was collected using the CrysAlisPro program [1]. The structure was solved with the ShelXS structure solution program using Patterson Method and refined with the ShelXL [2] refinement package using least-squares minimisation. H atoms were added using the riding models implemented in the SHELX system.

Comment

Cyclometalated complexes have attracted considerable attention due to their wide applications [4], [5], [6], [7]. Various methods for the preparation of these complexes have been developed, among which C—H activation is the simplest and most direct process [8], [9], [10]. In addition, C—H activation to form a cyclometalated complex has become an integral part of many catalytic cycles [11], [12], [13]. In recent years ruthenium complexes as highly active catalysts have successfully been applied to organic synthesis such as arylation, dehydrogenation and other coupling reactions [13], [14], [15]. As a continuation of our interest in the synthesis and application of cyclometalated complexes, we report the crystal structure of the title cyclometalated ruthenium complex.

The single-crystal X-ray analyses shows that the title complex adopts a typical “piano-stool” configuration with one chlorido ligand and one C,N-bidentate ligand as the three legs [16]. The pyridyl and benzyl ring are approximately coplanar as found in related cyclometalated complexes containing the same 2-(4-bromophenyl)pyridine ligand [17], [18]. Upon binding of the cyclometalated ligand to ruthenium a planar five-menbered chelate ring is formed. The chlorido ligand is almost perpendicular to the above planar chelate ring [N1–Ru1–Cl1 = 85.04(8)° and C7–Ru1–Cl1 = 88.17(8)°]. The Ru—C(arene) distances vary considerably from 2.151(3) Å to 2.267(3) Å. The Ru—N and Ru—C bond lengths of the title complex are similar to those of the related cyclometalated ruthenium complexes [3], [9], [14]. In the crystal there exist C—H⋯Cl hydrogen bonds, where the coordinated chlorido ligand forms hydrogen bonds with the adjacent C—H group of pyridyl ring (Cl⋯H = 2.913, and 2.919 Å) [19], [20], [21]. In addition, the bromine atom in benzyl ring also forms C—H⋯Br hydrogen bonds with the adjacent C—H group of arene ring (Br⋯H = 3.042 Å), thereby contributing to the formation of a 2D architecture that extends along the (0 1 0) plane 2D architecture.
