一个索烃的结构。[2]
Estructura cristalina de un catenano con un macrociclo ciclobis(paraquat-p-fenileno), publicada por Stoddart y colaboradores en Chem. Commun, 1991, 634 - 639

索烃是一个机械互锁分子，包含有两个或两个以上互锁的大环分子。除非环分子内部的共价键断裂，否则互锁的环不能够分开。索烃的英文名（Catenane）源自拉丁文的Catena，意思是“链”。索烃和其他机械互锁分子有着概念上的联系，例如：轮烷、分子扭结和分子博洛米尼结。最近，人们用机械键这样一个新的术语来描述索烃环之间的连接。

Catenane 索烃

Crystal structure of a catenane with a cyclobis(paraquat-p-phenylene) macrocycle reported by Stoddart and coworkers.[1]
Schematic animation of the template-directed synthesis of the bis-bipyridinium cyclophane / para-phenylene crown ether [2]catenane described in the text.
Crystal structure of a catenane reported by Sauvage and coworkers.[2]

A catenane is a mechanically-interlocked molecular architecture consisting of two or more interlocked macrocycles. The interlocked rings cannot be separated without breaking the covalent bonds of the macrocycles. Catenane is derived from the Latin catena meaning "chain". They are conceptually related to other mechanically interlocked molecular architectures, such as rotaxanes, molecular knots or molecular Borromean rings. Recently the terminology "mechanical bond" has been coined that describes the connection between the macrocycles of a catenane.
