摘要：

Neutral rhenium(V) and technetium(V) chelates with the tetradentate amine phenolate ligand N,N'-bis(2-hydroxybenzyl)-1,3-diamino-2(-4-nitrobenzyl)propane (H(2)L(1)) have been prepared from [MOCl(4)](-) complexes and structurally characterized. The ligand coordinates tetradentately with deprotonation of the phenolic oxygen atoms. [O=TcL(1)-O-L(1)Tc=O]. H2O crystallizes monoclinic in the space group P2(1)/c with a=10.633(2), b=13.705(1), c= 16.364(3) Angstrom; beta=94.65(1)degrees, Z=2. Two TcOL(1) units with each one terminal oxo core are connected by a mu-oxo ligand. The technetium atoms are situated in distorted octahedral coordination spheres. Two distinct Tc-O bond lenghts have been found for the almost linear O=Tc-O-Tc=O unit (Tc=O-(terminal): 1.655(7) Angstrom and Tc-O-(mu-oxo): 1.903(1)) Angstrom. The analogous rhenium compound crystallizes in the same space group with a=13.302(7), b=9.956(1), c= 17.535(9) Angstrom; beta=106.72(2)degrees, Z=2. The dimeric [O=ReL(1)-O-Re-1=O] complex has a structure which is very similar to that of the corresponding technetium compound.
