摘要:
Complexes of lanthanides with N,N'-bis(2-hydroxybenzylidene)-2-hydroxyphenylmethanediamine (HP were synthesized and investigated by the elemental, IR, magnetochemical, and thermogravimetric methods. Using the data obtained, they were found to have compositions Ln(2)L(2) . nH(2)O and La2L2 . MCl2 . 4H(2)O (Ln = La3+, Pr3+, Nd3+, Dy3+, Er3+; M = Cu2+, Co2+, Ni2+; n = 4, 6). Suggestions on their structures were made. In the interval of 20-140degreesC, these complexes were shown to be high-resistance semiconductors.
