Synthesis and Crystal Structure of Heteronuclear Lanthanum and Copper Complex with Diethylenetriaminepentaacetic Acid {La_4Cu_9(DTPA)_6(H_2O)_(16)·26H_2O}_n

摘要

The title complex has been synthesized and its single crystals were obtained from aqueous solution. The its molecular crystal structure shows there are two types of coordination environment for the lanthanum and copper ions. The coordination number of the La is 8 and 9 whereas those of Cu is 5 and 6 in these two environments.
