Synthesis of a metallamacrocyclic Re(CO)(3) complex using a tridentate bridging ligand

The reaction of [ReBr3(CO)(3)][NEt4](2) with 3-hydroxy-1,2,3-benzotriazine-4 (3 H) -one in the presence of base gave the ionic rhenium complex [ReBr(C7H4N3O2)(CO)(3)][NEt4] (2) which was crystallographically characterized. A neutral metallamacrocycle 3 was obtained upon abstraction of [NEt4]Br from complex 2. This complex cocrystallizes with an unusual C-3-symmetric [Ag(eta(1)-benzene)(3)(OH2)][BF4] complex as evidenced by single-crystal X-ray diffraction. (C) Wiley-VCH Verlag GmbH Co.
