Rod Packings and Metal−Organic Frameworks Constructed from Rod-Shaped Secondary Building Units

The principal structure possibilities for packing infinite rod-shaped building blocks are described.
Some basic nets derived from linking simple rods (helices and ladders) are then enumerated. We
demonstrate the usefulness of the concept of rod secondary building units in the design and synthesis of
metal−organic frameworks (MOFs). Accordingly, we present the preparation, characterization, and crystal
structures of 14 new MOFs (named MOF-69A−C and MOF-70−80) of 12 different structure types, belonging
to rod packing motifs, and show how their structures are related to basic nets. The MOFs reported herein
are of polytopic carboxylates and contain one of Zn, Pb, Co, Cd, Mn, or Tb. The inclusion properties of the
most open members are presented as evidence that MOF structures with rod building blocks can indeed
be designed to have permanent porosity and rigid architectures.

本描述阐述了无限长棒状构建块在包装结构中的主要可能性。随后，通过对简单棒状元件（螺旋和梯子）的连接，列举了一些基本网络。我们展示了棒状次级构建单元在金属-有机框架（MOFs）设计和合成中的概念价值。因此，我们展示了14种新型MOFs（命名为MOF-69A−C和MOF-70−80）的制备、表征和晶体结构，这些MOFs属于12种不同的结构类型，隶属于棒状包装母体，并展示了它们的结构与基本网络之间的关系。所述MOFs为多边形羧酸盐，并含有Zn、Pb、Co、Cd、Mn或Tb中的一种。最开放成员的包含性质作为证据，表明由棒状构建块构成的MOF结构确实可以被设计成具有永久多孔性和刚性架构。
