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-H₂chdc), 2,4-diamino-6-phenyl-1,3,5-triazine (phdat) as well as CoCl₂·6H₂O, CdCl₂·2.5H₂O 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 Co₂(CO₂)₄/Cd₂(CO₂)₄ units, which are further connected to 1D chain structures by μ₄:η¹:η¹:η¹:η¹ 1,4-chdc^2– ligands and extended into a 3D structures via different hydrogen bonding and π…π stacking interactions. Furthermore, compound 1 exhibits antiferromagnetic behavior and compound 2 displays luminescent behavior at solid state. - Graphical abstract: Two isomorphous coordination compounds 1–2 have been synthesized and characterized by XRD, IR spectra and TGA etc. Compound 1 and 2 display antiferromagnetic behavior and luminescent behavior respectively. - Highlights: • Two novel polymers based on 1,4-cyclohexanedicarboxylic acid have been synthesized. • Compounds 1 and 2 feather 1D chain structure built up from paddle-wheel SBUs. • The magnetism of 2 is investigated. • The electrochemical property and luminescent property of 1 are investigated.
