Synthesis and crystal structure of complexes of erbium(III) picrate with N,N,N′,N′-tetraphenyl-3,6,9-trioxaundecanediamide
摘要:
Reaction of erbium picrate with N,N,N',N'-tetraphenyl-3,6,9-trioxaundecanediamide (TTD) yielded [Er(Pic)(3)(TTD)]. Its crystal structure shows that the Er-III ion is coordinated to five oxygen atoms of TTD, three oxygen atoms of two picrates and one oxygen atom of H2O giving a coordination number of nine. The TTD molecule acts as a multidentate ligand forming a ring-like coordination structure similar to those of crown compounds. (C) 1997 Elsevier Science Ltd.
