The invention discloses a (R, R)-1,2-diphenylethylenediamine nickel azide complex. The (R, R)-1,2-diphenylethylenediamine nickel azide complex has a chemical formula of [Ni(L)2(N3)] infinity ClO4.0.5H2O, wherein L is a chiral bidentate nitrogen-containing organic ligand. The preparation method comprises the following steps: placing a methanol solution as an underlayer in which nickel perchlorate and chiral bidentate nitrogen-containing organic ligand L are dissolved into a reaction vessel, adding a mixed solution of methanol and water as an intermediate buffer layer, slowly adding a water solution as an uppermost layer in which sodium azide is dissolved into the reaction vessel, standing for 5 days, filtering, washing and carrying out vacuum drying to obtain the target product. A novel one-dimensional chain nickel complex is prepared by using azide anion as a bridging ligand, the preparation process is simple, the reaction is carried out under a normal temperature and a normal pressure, the posttreatment is easily performed, and the yield is high and can reach 83%. The (R, R)-1,2-diphenylethylenediamine nickel azide complex has good ferroelectric property and has potential broad application prospects in the field of information storage as a novel ferroelectric material.
