| Abstract | Hydrothermal reaction of either cobalt or cadmium nitrate, D-camphoric acid (H(2)cam), and conformationally flexible dipyridylamide ligands produced five coordination networks which were structurally characterized by single-crystal X-ray diffraction. {[Co-2.DL-cam)(2).bdn)]center dot 2H(2)O}(n) (1, bdn = N, N'-(butane-1,4-diyl) dinicotinamide) possesses {Co-2(OCO)(4)} paddlewheel dimer-based [Co-2(DL-cam)(2)] grid layers pillared by bdn ligands into a 6-connected 4(12)6(3) pcu network. In contrast, the cadmium analog {[Cd-2(D-cam) (2)(bdn)(2)]center dot 5H(2)O}(n) (2) shows {Cd-2(OCO)(2)} dimer-based [Cd-2(D-cam)(2)] layers tethered by bdn ligands into an 8-connected 4(24)6(4) bcu network. {[Co-2(D-cam)(2)(pdn)]center dot 2H(2)O}(n) (3, pdn = N, N'-(propane-1,3-diyl) dinicotinamide) manifests a self-penetrated 4(4)6(8)10 mab network in contrast to 1, and retains chirality. {[Cd-2(D-cam)(2)(pdn)]center dot H2O}(n) (4) manifests {Cd-2(OCO)(4)} paddlewheel dimer-based [Cd-2(D-cam)(2)] grids, connected by exotridentate pbn ligands into a unique 3,7-connected 3D network with (3 center dot 5(2))(3(2)4(4)5(6)6(8)7) topology derived from a rare non-self-penetrated 4(9)6(6) acs topology sublattice. {[Co-2(DL-cam)(2)(pedn)] center dot 2H(2)O)(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. |
