CuBr<sub>2</sub> complexes with 3,5-disubstituted pyridine ligands
Reaction of copper(II) bromide with 3,5-di-chloro-pyridine (3,5-Cl<sub>2</sub>py) or 3,5-di-methyl-pyridine (3,5-Me<sub>2</sub>py) led to the isolation of the coordination polymers <i>catena</i>-poly[[bis-(3,5-di-chloro-pyridine)-copper(II)]-di-μ-bromido], [CuBr<sub>2</sub>(C<sub>5</sub>H<sub>3</sub>Cl<sub>2</sub>N)<sub>2</sub>] <sub><i>n</i></sub> or [CuBr<sub>2</sub>(3,5-Cl<sub>2</sub>py)<sub>2</sub>] <sub><i>n</i></sub> (<b>1</b>), and <i>catena</i>-poly[[bis-(3,5-di-methyl-pyridine)-copper(II)]-di-μ-bromido], [CuBr<sub>2</sub>(C<sub>7</sub>H<sub>9</sub>N)<sub>2</sub>] <sub><i>n</i></sub> or [CuBr<sub>2</sub>(3,5-Me<sub>2</sub>py)<sub>2</sub>] <sub><i>n</i></sub> (<b>2</b>), respectively. The structures are characterized by bibromide-bridged chains [<i>d</i>(av.)<sub>Cu⋯Cu</sub> = 3.93 (9) Å]. In <b>1</b>, the chains are linked perpendicular to the <i>a</i> axis by non-classical hydrogen bonds and halogen bonds, while in <b>2</b>, only non-classical hydrogen bonds are observed.
