KGaA，魏因海姆和USF-1网络的两个急性。[3g]这些事实表明，仅基于正方形平面节点的网络的拓扑结构强烈依赖于相邻节点的方向;因此，仅基于正方形平面节点的特定网络可以通过控制二面角来组装。一些结构已经成功地通过将刚性正方形平面二级结构单元（SBU）与特定几何形状的配体定向来合成。[4c]相比之下，除了取代基之外，1和2中的配体非常相似，并且二面角在甲基的情况下约为308，在较大的丙基的情况下约为908。因此，我们可以认为这些三唑类化合物取代基的空间排斥可能会增强相邻方形平面节点之间的二面角。由于所有这样的4-连通网络可以被增强到相关的3-连通网络，这项工作也说明了一种替代策略，使用三角平面构建块来构建这样有趣的网络，而不是通常的方法，涉及正方形平面units.In总结，我们已经描述了两个前所未有的铜（i）三唑配位聚合物形成前所未有的铜介导的腈和氨的环加成反应。这些化合物形成了具有新颖拓扑结构的3-连通网络，这对理解相关网络之间的关系具有重要意义，并且一锅反应可能成为合成三唑衍生物的新合成方法。
207 Angew. Chem. Int. Ed. 2004, 43, 206–209 www. angewandte. org 2004 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim and two acute for USF-1 networks.[3g] These facts indicate that the topology of a network based solely on square-planar nodes depends strongly on the orientation of adjacent nodes; therefore, a specific network based solely on square-planar nodes can be assembled by control of the dihedral angles. A few structures have been successfully synthesized by directing rigid square-planar secondary building units (SBUs) with ligands of specific geometry.[4c] In contrast, the ligands in both 1 and 2 are very similar except for the substituents, and the dihedral angles are about 308 in the case of methyl groups and 908 in the case of the larger propyl groups, respectively. Consequently, we may suggest that steric repulsion of the substituents of these triazolates may enforce the dihedral angles between adjacent square-planar nodes. Since all such4-connected nets can be augmented to related 3-connected nets, this work also illustrates an alternative strategy of using trigonal-planar building blocks to build such intriguing networks, rather than the usual methods involving square-planar units.In summary, we have described two unprecedented copper (i) triazolate coordination polymers formed by unprecedented copper-mediated cycloadditions of nitriles and ammonia. These compounds form 3-connected networks with novel topologies that have implications for understanding the relationship between related nets, and the one-pot reaction may serve as a new synthetic approach for the synthesis of triazole derivatives.
