This communication describes the syntheses of the quasi-one-dimensional mixed-halogen-bridged NiIII complexes with strong electron correlation [Ni(chxn)2Cl1-xBrx] (NO3)2 and the tuning of the spin density wave strengths of these compounds. If the Cl 3p and Br 4p make one band in the compounds, we should observe a single peak in the electronic spectra. As a result, we should observe the single peak from 1.45 to 2.00 eV depending on the mixing ratios of Cl and Br ions. Therefore, the Cl 3p and Br 4p make one band. Then, we have succeeded in tuning the spin density wave strengths of the NiIII complexes with the strong electron correlation by mixing the bridging halogen ions successively.
