Abstract

Compounds 1 and 2 are similar coordination polymers of bibromide bridged chains of Cu^II ions with 3,5-disubstituted pyridine molecules in the axial sites. The chains lie parallel to the a axis and are linked into a tri-periodic network via non-classical hydrogen bonds.

Reaction of copper(II) bromide with 3,5-dichloropyridine (3,5-Cl₂py) or 3,5-dimethylpyridine (3,5-Me₂py) led to the isolation of the coordination polymers catena-poly[[bis(3,5-dichloropyridine)copper(II)]-di-μ-bromido], [CuBr₂(C₅H₃Cl₂N)₂]_n or [CuBr₂(3,5-Cl₂py)₂]_n (1), and catena-poly[[bis(3,5-dimethylpyridine)copper(II)]-di-μ-bromido], [CuBr₂(C₇H₉N)₂]_n or [CuBr₂(3,5-Me₂py)₂]_n (2), respectively. The structures are characterized by bibromide-bridged chains [d(av.)_Cu⋯Cu = 3.93 (9) Å]. In 1, the chains are linked perpendicular to the a axis by non-classical hydrogen bonds and halogen bonds, while in 2, only non-classical hydrogen bonds are observed.

期刊介绍： Acta Crystallographica Section E: Crystallographic Communications is the IUCr''s open-access structural communications journal. It provides a fast, simple and easily accessible publication mechanism for crystal structure determinations of inorganic, metal-organic and organic compounds. The electronic submission, validation, refereeing and publication facilities of the journal ensure rapid and high-quality publication of fully validated structures. The primary article category is Research Communications; these are peer-reviewed articles describing one or more structure determinations with appropriate discussion of the science.
