Abstract

Heterodinuclear complexes of Co(II)/Zn(II) and Mn(II)/Zn(II) with pyridine-2,6-dicarboxylic acid as a ligand (H2dipic, dipicolinate) have been synthesized yielding of reddish purple colour of Co(II)/Zn(II) dipicolinic crystal an reddish colour of Mn(II)/Zn(II) dipicolinic crystal. The determination of elements composition (%) of complex compound using atomi absorption spectroscopy and CHN elemental analyzer (C = 28.96; H = 3.7; N = 5.42; Co = 10.15 Mn = 9.47 Zn = 11.26) showed that the molecular formula of Co(II) complex compound is [Zn(H2O)5Co(dipic)2].H2O, while that of Mn(II) complex compound is [Zn(H2O)5Mn(dipic)2].H2O. The IR spectrum of the Co(II) and Mn(II) complexes showed a typical vibration absorption in the wavenumber of 3082 cm-1 indicating of Co(II)/Zn(II) dipicolinic and Mn(II)/Zn(II) dipicolinic have been formed. A brine shrimp letality test (BSLT) used to determine the toxicity of complexes showed that LC50 of Co(II) complex and Mn(II) complexes were 283.71 and 354.94 mg/L, respectively.
