STUDY ON THE COORDINATION COMPOUNDS OF RARE EARTHS WITH DIPEPTIDE-COORDINATION OF RARE EARTHS WITH DL-ALANYL-ALANINE
摘要:
In this paper protonation constants of the title lisand and stability constants of its coordination compounds with rare earths have been determined by potentiometric titration at 25±；0.1℃ and ionic strength of 0.10mol.dm-3 NaClO4. The coordination of rare earths with DL-alanyl-alanine has been discussed. The stability of the coordination compound shows "tetrad effect". The position for yttrium shifts from its usual Bo-Er region to the vicinity of Tb.
