The purpose of the research is to find out the synthesis, formula and characteristic of complex of Nickel(II) with hydantoin (hyd). Complex of nickel(II) with hydantoin have been synthesized in 1 : 1 mole ratio of metal to ligan in methanol.The formula of complex which are predicted from analysis of % Ni in complex by Atomic Absorption Spectroscopy (AAS) is Ni(hyd)2(H2O)3.SO4. Ratio of cation and anion of complex is measured by conductivitymeter correspond to 1: 1. The thermal analysis is determined by Differential Thermal Analyser (DTA) indicate that complex contain some hydrate, thus possibility formula of complex is [Ni(hyd)2(H2O)2]SO4.H2O (Diaquadihydantoinnikel(II) sulfat monohidrat). Data of infra red spectra show a shift of N-H group and tertier N group138absorption and indicate this functional group coordinated to the center ion. Magnetic Suscepbility measurement show that the complex is paramagnetic with μeff = 3.2 BM. The UV-Vis spectra appear do to 2 transition peak on  = 740 nm (13,513 cm-1) and 405 nm (24,691 cm-1. The peak indicate that structure of complex is octahedral with transition 3A2g → 3T1g(P)(ν2) andtransition 3A2g → 3T1g(F)(ν3). One peak which is not appear is transition 3A2g → 3T2g(F)(ν1) which also estimate of 10 Dq (Δ0) is 103.615 kJ mol-1.
