The oxovanadium(IV) complex of oxodiacetic acid (H<sub>2</sub>ODA) and 2,2’-bipyridine (bipy) of stoichiometry [VO(ODA)(bipy)]⋅H<sub>2</sub>O, was thoroughly characterized by infrared, Raman and electronic spectroscopies. The biological activity of the complex on the cell proliferation was tested on osteoblast-like cells (MC3T3E1 osteoblastic mouse calvaria-derived cells and UMR106 rat osteosarcoma-derived cells) in culture. The complex caused inhibition of cellular proliferation in both osteoblast-like cells in culture, but its action was statistically stronger in the tumoral cells. This effect was specially marked with increasing concentrations of the complex. Based on these preliminary biological results, [VO(ODA)(bipy)]⋅H<sub>2</sub>O can be considered as a good candidate to be further investigated in relation to cancer treatment.

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
