Abstract

Reactions of solutions of 1,1′-(alkane-1,х-diyl)-bis(pyridinium) dibromides ((PyCx)Br2) with 1M Br2 in HBr result in the formation of tribromides (PyCx)(Br3)2 (x = 3 (1), 4 (2), 5 (3)) and pentabromide (PyC6)(Br5)2 (4). Their structures are investigated by X-ray crystallography. The structure of 4 contains noncovalent Br⋯Br interactions linking \(\text{Br}_{5}^{-}\) anions into two-dimensional supramolecular associates.

摘要

1,1'-(alkane-1, х -diyl)-bis(pyridinium) 二溴化物 ((PyC x )Br 2 ) 与 1M Br 2在 HBr 中的反应导致形成三溴化物 (PyC x )(Br 3 ) 2 ( x  = 3 ( 1 ), 4 ( 2 ), 5 ( 3 )) 和五溴化物 (PyC 6 )(Br 5 ) 2 ( 4 )。通过 X 射线晶体学研究它们的结构。4的结构包含非共价Br⋯Br相互作用连接\(\text{Br}_{5}^{-}\) 阴离子转化为二维超分子缔合物。
