(2,2′-Biquinoline-κ2 N,N′)dibromidopalladium(II)
نویسنده
چکیده
The Pd(II) ion in the title complex, [PdBr(2)(C(18)H(12)N(2))], is four-coordinated in a distorted square-planar environment by the two N atoms from the chelating 2,2'-biquinoline (Biqu) ligand and two mutually cis Br(-) anions. The Biqu ligand is not planar, the dihedral angle between the quinoline systems being 17.2 (2)°. In the crystal, the complex mol-ecules are connected by C-H⋯Br hydrogen bonds, forming chains along the c axis. When viewed down the b axis, successive chains are stacked in opposite directions. Intra-molecular C-H⋯Br hydrogen bonds are also observed.
