Abstract

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. [Cd2(trans-12cdc)2(4-bpmp)]n (2, trans-12cdc = trans-1,2-cyclohexanedicarboxylate) displays a unique 4,5-connected layered (46)(4664) topology with embedded [Cd2(trans-12cdc)2] ribbon motifs. {[Cd(cis-12chedc)(4-bpmp)]·0.25H2O}n (3, cis-12chedc = cis-1,2-cyclohex-4-enedicarboxylate) manifests a 3D 3,5-connected self-penetrated network with an unprecedented (426)(426583) topology. Thermal decomposition, luminescent, and nitroaromatic detection properties of these three new materials are discussed.
