摘要：

The coordination structure of lanthanide(III) nitrate complexes with N,N'-dimethyl-N, N'-dibutylmalonamide (DMDBMA) was studied by nuclear magnetic resonance, Fourier transform IR and molar conductivity measurements. It was found that the formula of lanthanide(III)-DMDBMA complexes is Ln(NO3)(3) . 2DMDBMA, in which the DMDBMA coordinates to the Ln(III) ion with the two carbonyl groups in a bidentate manner, and the coordination number of Ln(NO3)(3) . 2DMDBMA is ten. Moreover, a structural change between the lighter and heavier complexes is suggested.
