• This paper reports two new coordination polymers based on d-camphoric acid.
• Both the compounds feather two-dimensional layered networks built up from paddle-wheel SBUs.
• The magnetism and electrochemical property are investigated.
By hydrothermal method, two new coordination polymers [Co(ca)(phdat)]n (1), [Ni(ca)(phdat).0.125H2O]n (2) (H2ca=d-camphoric acid, phdat=2-phenyl-4,6-diamino-1,3,5-triazine) have been achieved and structurally characterized by IR, elemental analyses, X-ray single-crystal diffraction and TGA. The X-ray single-crystal diffraction reveals that compounds 1 and 2 are isostructural, both of which exhibit two-dimensional layered network built up from paddle-wheel Co2(CO2)4/Ni2(CO2)4 SBUs by ca2− ligand. In the existence of π…π stacking interactions between triazine rings and phenyl rings, the 3D networks are constructed with the hanging phdat filled between the neighboring layers. Furthermore, compounds 1–2 exhibit antiferromagnetic behavior and compound 2 displays a good activity for methanol oxidation.
Two new coordination compounds 1–2 have been synthesized and characterized by single-crystal X-ray diffractions, IR spectra, elemental analyses, thermogravimetric analyses, magnetic and electrochemical measurement.Figure optionsDownload as PowerPoint slide
