Hydrothermal reaction of either cobalt or cadmium nitrate, D-camphoric acid (H₂cam), and conformationally flexible dipyridylamide ligands produced five coordination networks which were structurally characterized by single-crystal X-ray diffraction. {[Co₂(DL-cam)₂(bdn)]·2H₂O}_n (1, bdn = N,N′-(butane-1,4-diyl)dinicotinamide) possesses {Co₂(OCO)₄} paddlewheel dimer-based [Co₂(DL-cam)₂] grid layers pillared by bdn ligands into a 6-connected 4¹²6³pcu network. In contrast, the cadmium analog {[Cd₂(D-cam)₂(bdn)₂]·5H₂O}_n (2) shows {Cd₂(OCO)₂} dimer-based [Cd₂(D-cam)₂] layers tethered by bdn ligands into an 8-connected 4²⁴6⁴bcu network. {[Co₂(D-cam)₂(pdn)]·2H₂O}_n (3, pdn = N,N′-(propane-1,3-diyl)dinicotinamide) manifests a self-penetrated 4⁴6⁸10 mab network in contrast to 1, and retains chirality. {[Cd₂(D-cam)₂(pdn)]·H₂O}_n (4) manifests {Cd₂(OCO)₄} paddlewheel dimer-based [Cd₂(D-cam)₂] grids, connected by exotridentate pbn ligands into a unique 3,7-connected 3D network with (3·5²)(3²4⁴5⁶6⁸7) topology derived from a rare non-self-penetrated 4⁹6⁶acs topology sublattice. {[Co₂(DL-cam)₂(pedn)]·2H₂O}_n (5, pedn = N,N′-(pentane-1,5-diyl)dinicotinamide) shows a hybrid structure of discrete slabs of 3D pcu network with interleaved 2D hxl (3,6) layers at random intervals, instead of the self-penetrated mab network seen in 3. The specific coordination environments and dipyridylamide lengths result in control of topology and self-penetration in this series of coordination networks. The cadmium complexes 2 and 4 were assayed for luminescent and nitrobenzene detection properties. Thermal properties of 1–5 are also discussed.

钴和镉樟脑协调配合物的手性和级联控制†

硝酸钴或硝酸镉，D-樟脑酸（H ₂ cam）和构象上灵活的二吡啶酰胺配体的水热反应产生了五个配位网络，其结构通过单晶X射线衍射表征。{[Co ₂（DL -cam）₂（bdn）]·2H ₂ O} _n（1，bdn = N，N '-（（丁烷-1,4-二基）丁二烯酰胺））拥有{Co ₂（OCO）₄ }桨轮基于二聚体的[Co ₂（DL -cam）₂ ]网格层，由bdn配体立柱成6个相连的4 ¹²6 ³ pcu网络。与此相反，镉类似物{[CD ₂（d -cam）₂（BDN）₂ ]·5H ₂ ö} _Ñ（2）示出了{镉₂（OCO）₂ }为基础的二聚体- [CD ₂（d -cam）₂ ]层由bdn配体束缚成8-连接的4 ²⁴ 6 ⁴ bcu网络。{[Co ₂（D- cam）₂（pdn）]·2H ₂ O} _n（3，pdn = N，N相对于1，'-（丙烷-1,3-二基）二烟酰胺）表现出自穿透的4 ⁴ 6 ⁸ 10 mab网络，并保留了手性。{[Cd ₂（D -cam）₂（pdn）]·H ₂ O} _n（4）表示{Cd ₂（OCO）₄ }基于桨轮二聚体的[Cd ₂（D -cam）₂ ]网格，通过将pbn配位体转移到一个独特的3,7连接的3D网络中，该网络具有（3·5 ²）（3 ² 4 ⁴ 5 ⁶ 6 ⁸7）从罕见的非自穿透4 ⁹ 6 ⁶ acs拓扑子晶格派生的拓扑。{[Co ₂（DL -cam）₂（pedn）]·2H ₂ O} _n（5，pedn = N，N '-（戊烷-1,5-二基）dinicotinamide）显示了3D离散平板的混合结构具有随机间隔交错2D hxl（3,6）层的pcu网络，而不是3中看到的自穿透mab网络。特定的配位环境和二吡啶基酰胺长度可控制这一系列配位网络中的拓扑结构和自穿透。测定了镉络合物2和4的发光和硝基苯检测性能。还讨论了1-5的热特性。
