摘　　要：报道了用古埃（Ｇｏｕｙ）磁天平法测定Ｋ＿２［Ｆｅ（Ｃ＿２Ｏ＿４Ｏ＿４）＿３］３Ｈ＿２Ｏ摩尔磁化率，磁场强度Ｈ用ＣＴ５型特斯拉计直接测量或由已知单位质量磁化率的莫尔盐（ＮＨ＿４）＿２ＳＯ＿４，·ＦｅＳＯ＿４·６Ｈ＿２Ｏ间接标定，根据测得的摩尔磁化率Ｘ＿Ｍ，求出配合物分子的磁矩Ｕ＿ｍ和未成对电子数，推断Ｋ＿３［Ｆｅ（Ｃ＿２Ｏ＿４）＿３］·３Ｈ＿２Ｏ的配位键类型。The paper reports a method, in which the molecular magnetic susceptibility (X_m)of K_3[Fe(C_2O_4)_3] ·3H_2O is measured by Gouy magnetic-balance and the magnetic field intensity( H)is mea-sured by CT5 divectly or(NH_4)_2SO_4.FeSO_4· H_2O that the magnetic susceptibility is known in direct-ly, By measuring X_y,the magnetic moment(U_m)and unpaired elwctron number of K_3 [ Fe(C_2O_4)_3]·3H_2O have been calculated,which shows that the complex is eleetrovalent structure.
