The construction of novel molecules with unprecedented alignments of the constituent elements has revolutionized the field of functional materials. The arrangement of two or more planar subunits in a mutually perpendicular fashion is a frequently encountered approach to produce novel functional materials. Previous examples of such materials can be categorized into two well-investigated families: -conjugated and dumbbell-shaped structures, wherein the two planes are aligned orthogonally a single atom or an axis, respectively. This article describes a third family: reaction of [Pd(CN Bu)] with SnMe or GeMe afforded a PdSn cluster and a PdGe cluster that consist of two mutually bisecting perpendicular planes. In the PdSn cluster, the two equivalent PdSn planes share three palladium atoms that include a dihedral angle of 85.6°.
构建具有前所未有的组成元素排列方式的新型分子，彻底改变了功能材料领域。以相互垂直的方式排列两个或更多平面亚基是制备新型功能材料时常用的方法。此类材料的先前实例可分为两个经过充分研究的家族：π共轭和哑铃形结构，其中两个平面分别相对于单个原子或轴正交排列。本文描述了第三个家族：[Pd(CNtBu)2]与SnMe4或GeMe4反应生成了由两个相互平分的垂直平面组成的PdSn簇和PdGe簇。在PdSn簇中，两个等效的PdSn平面共享三个钯原子，其包含85.6°的二面角。
