研究了组成为RE(His)(NO3 )3 ·H2O(RE= La~Nd,Sm ~Lu,Y;His= L-α-histidine)固态配合物的拉曼光谱。结果表明,配合物中RE3+ 与羧基氧原子配位,氨基和味唑环均未参与配位,NO-3 为双齿配位。配合物羧基振动峰的Δνas-sCOO- 与镧系离子的原子序数作图服从Oddo-Harkins规律
The Raman spectra of solid-state complexes with RE (His) (NO3) 3 · H2O (RE = La ~ Nd, Sm ~ Lu, Y; His = L-α-histidine) were studied. The results showed that the coordination between RE3 + and carboxyl oxygen atom in the complex did not take place in the amino group and the imidazole ring, and NO-3 was bidentate. Complexes carboxyl vibration peak Δνas-sCOO- and lanthanide ion atomic number plot obeys the Oddo-Harkins law
