Abstract
The PdII ion in the title complex, [PdBr2(C18H12N2)], 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 molecules 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. Intramolecular C—H⋯Br hydrogen bonds are also observed.
Highlights

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
Summary
The PdII ion in the title complex, [PdBr2(C18H12N2)], is fourcoordinated in a distorted square-planar environment by the two N atoms from the chelating 2,20 -biquinoline (Biqu) ligand and two mutually cis Br anions. The Biqu ligand is not planar, the dihedral angle between the quinoline systems being. The complex molecules 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. Intramolecular C—H Br hydrogen bonds are observed
