Rhodizonic acid (H2RHOD) was reacted with Co(PF6)2.6H2O in the presence of pyridine modified large macrocyclic ligand (H2Lopy) and triethylamine in N,N-dimethylformamide under argon atmosphere. Instead of [Co4(RHOD)2(Lopy)](PF6)2 (1), the main product of this reaction was a crystalline compound [Co4(CROC)2(Lopy)](PF6)2, which was isolated in low yield (< 25%). Based on the elemental analysis, ESI-mass spectroscopy, and infrared spectrum, the isolated compound was confirmed to be [Co4(CROC)2(Lopy)](PF6)2 (2), where CROC2- is croconate anion C5O52-.Journal of Bangladesh Academy of Sciences, Vol. 40, No. 2, 101-108, 2016

In a sustained search for novel antimicrobial agents as weaponry in the war against infectious diseases, resulting in improved survivability for both humans and their domestic animals, the present study demonstrates an efficient synthesis of N,N-dimethylaminophenyl substituted pyrazole carbothioamide derivatives. The synthesis involves (3+2) cycloaddition of chalcones with hydrazinecarbothioamide hydrochloride in the presence of the amberlyst-15 catalyzed at room temperature. The structures of new compounds were characterized by spectroscopic analysis. Furthermore, the synthesized new compounds 5(a-g) were assessed in vitro for their antimicrobial susceptibilities. The results indicate that compounds 5a found potent against tested bacteria species; 5b and 5c show excellent inhibition against the tested fungi and bacteria species. Therefore, these could act as antifungal and antibacterial leads for further investigations.
