Ni(NO 3 ) 2 .6H 2 O and diphenylamine formed a complex compound in 1:6 mole ratio of metal to ligand in methanol. The forming of the complex was indicated by shifting of maximum wavelength in UV-Vis spectra. Analysis of the nickel percentage in the complex by Atomic Absorption Spectroscopy (AAS) showed an empirical formula of the complex was Ni(diphenylamine) 4 (NO 3 ) 2 .6H 2 O. The conductivity measurement of the complex showed the charge ratio of cation and anion = 1:1. It meant that NO 3 - was coordinated to the Ni 2+ center ion and likewise as a counter ion. The formula of complex was approximated [Ni(diphenylamine) 4 (NO 3 )(H 2 O)](NO 3 ).5H 2 O. Based on infrared spectra, it releaved diphenylamine as monodentate ligand which bind to nickel(II) through the secondary NH functional groups. Electronic spectra showed a transition peak at 25252 cm -1 and 13802 cm -1 which indicating octahedral geometry. The complex was paramagnetic with μ eff = 2.99 BM.
