Cobalt(II)-Nicotinamide had been synthesized mole ratio in 1 : 2 of metal to the ligand in methanol. The complex was characterized by atomic absorption spectrophotometer (AAS), conductometer, UV-Vis spectrophotometer, MSB (magnetic susceptibility balance) and FT-IR spectrophotometer. The result of AAS showed that cobalt(II) in the complex was 14,40%. The molar conductivity showed that the complex was 2 to 1 electrolyte. UV-Vis spectra appeared a transition peak of third transition 4T1g(F) → 4T1g(P). The momen magnetic showed that the complex was paramagnetic. The infrared spectral indicate that groups of primary N-H and carbonyl were coordinated to the center ion of Co(II). The complex formula was estimated as [Co(Nicotinamide)2(H2O)2]Cl2 and probably octahedral.
