Hydrothermal reaction of cadmium nitrate, bis(4-pyridylmethyl)piperazine (4-bpmp), and a variety of cyclohexyldicarboxylate ligands generated three new coordination polymer solids that were structurally characterized via single-crystal X-ray diffraction. [Cd( cis -13cdc)(4-bpmp)] n ( 1 , cis -13cdc = cis -1,3-cyclohexanedicarboxylate) shows a sawtooth (4,4) grid topology. [Cd 2 ( trans -12cdc) 2 (4-bpmp)] n ( 2 , trans -12cdc = trans -1,2-cyclohexanedicarboxylate) displays a unique 4,5-connected layered (4 6 )(4 6 6 4 ) topology with embedded [Cd 2 ( trans -12cdc) 2 ] ribbon motifs. {[Cd( cis -12chedc)(4-bpmp)]·0.25H 2 O} n ( 3 , cis -12chedc = cis -1,2-cyclohex-4-enedicarboxylate) manifests a 3D 3,5-connected self-penetrated network with an unprecedented (4 2 6)(4 2 6 5 8 3 ) topology. Thermal decomposition, luminescent, and nitroaromatic detection properties of these three new materials are discussed.
