Abstract
In the title compound, [ZnBr2(C18H12N2)], the ZnII atom is four-coordinated in a distorted tetrahedral configuration by two N atoms from the 2,2′-biquinoline ligand and two terminal Br atoms. The crystal packing is stabilized by weak intermolecular C—H⋯Br hydrogen bonds and extensive intermolecular π–π contacts between the pyridine and benzene rings [centroid–centroid distances = 3.775 (4), 3.748 (4), 3.735 (4), 3.538 (4), 3.678 (4) and 3.513 (4) Å].
Highlights
In the title compound, [ZnBr2(C18H12N2)], the ZnII atom is four-coordinated in a distorted tetrahedral configuration by two N atoms from the 2,20 -biquinoline ligand and two terminal
Numerous complexes have been prepared with the bidentate ligand 2,2′-biquinoline (2,2′-biq) such as that of iron (Rahimi et al, 2009), iridium (Yoshikawa et al, 2003), platinum (Okabe & Muranishi 2005), copper (Moreno et al, 2007; Zhou & Ng 2006), silver (Bowmaker et al, 2005), nickel (Kou et al, 2008; Butcher & Sinn 1977) and palladium (Muranishi et al, 2005)
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
R factor = 0.070; wR factor = 0.150; data-to-parameter ratio = 21.5.
