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.

CuBr2配合物与3,5-二取代吡啶配体。

溴化铜（II）与3,5-二氯吡啶（3,5- cl2py）或3,5-二甲基吡啶（3,5- me2py）反应，分离得到配位聚合物链-聚[[双-（3,5-二氯吡啶）-铜（II）]-二μ-溴]，[CuBr2(C5H3Cl2N)2] n或[CuBr2(3,5- cl2py)2] n(1)和链-聚[[双-（3,5-二甲基吡啶）-铜（II）]-二μ-溴]，[CuBr2(C7H9N)2] n或[CuBr2(3,5- me2py)2] n(2)。这些结构的特征是bi溴化物桥链[d(av)]。Cu⋯Cu = 3.93 (9) Å]。在图1中，链由非经典氢键和卤素键垂直于a轴连接，而在图2中，只观察到非经典氢键。

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.
