Artykuł
The crystal structure of [C(NH2)3]2[Nd(dtpa)(H2O)]·7H2O (H5dtpa=diethylenetriaminepentaacetic acid) has been determined. Electronic absorption spectra of a single crystal of the [C(NH2)3]2[Nd(dtpa)(H2O)]·7H2O compound were measured at room and liquid helium temperatures. In order to investigate the formation and structure of NdIII–dtpa species occurring in solution, the spectral results for the crystal were compared with those of the NdIII–dtpa (1:1) complex in solution. The analysis of spectral properties of this system may be applied for solutions of coordination chemistry problems encountered in lanthanide polyaminopolycarboxylates.
