The assembly of two isomorphous coordination compounds based on 1,4-cyclohexanedicarboxylic acid and 2,4-diamino-6-phenyl-1,3,5-triazine

The compounds [Co(e,a-cis-1,4-chdc)(phdat)](n) (1) and [Cd(e,a-cis-1,4-chdc)(phdat)](n) (2) have been synthesized under hydrothermal method by using 1,4-cyclohexanedicarboxylic acid (1,4-H(2)chdc), 2,4-diamino-6-phenyl-1,3,5-triazine (phdat) as well as CoCl2 center dot 6H(2)O, CdCl2 center dot 2.5H(2)O respectively and characterized by IR spectra, X-ray single-crystal diffraction, powder X-ray single-crystal diffraction (PXRD), elemental analyses and thermogravimetric analyses (TGA). The results show the compounds 1 and 2 are isomorphous and exhibit paddle-wheel dinuclear Co-2(CO2)(4)/Cd-2(CO2)(4) units, which are further connected to 1D chain structures by mu(4):eta(1):eta(1):eta(1):eta(1) 1,4-chdc(2-) ligands and extended into a 3D structures via different hydrogen bonding and pi...pi stacking interactions. Furthermore, compound 1 exhibits antiferromagnetic behavior and compound 2 displays luminescent behavior at solid state.
