Dibromido(2,2′:6′,2′′-terpyridine-κ3N,N′,N′′)zinc(II)
Abstract
In the title compound, [ZnBr2(C15H11N3)], the ZnII ion is five-coordinated by the three N atoms from a 2,2′:6′,2′′-terpyridine ligand (terpy) and two bromide anions in a distorted trigonal bipyramidal configuration. Each molecule is situated on a twofold rotational axis that passes through the ZnII ion and the central ring of the terpy ligand. In the crystal structure, aromatic π–π interactions between terpy ligands [centroid–centroid distances = 3.6265 (9) Å] link molecules into stacks propagated in the [001] direction.
