Intercalation of nickel and cobalt thiabendazole complexes into montmorillonite

The intercalation of nickel and cobalt thiabendazole complexes into montmorillonite was investigated by two strategies. The first strategy consisted of exchanging sodium montmorillonite (Na+–Mt) by nickel or cobalt ions followed by complexation of these cations by thiabendazole. The second method was the direct exchange of the sodium ions by the Ni– or Co–thiabendazole complexes. The thiabendazole–montmorillonite complexes were investigated by X-ray diffraction, FTIR and TGA analysis.

► Ni2+ and Co2+ montmorillonite coordinated thiabendazole within the interlayer space. ► [Co(tbz)2]2+ and [Ni(tbz)2]2+ complexes were also directly intercalated into Na+–Mt.
