High-Spin M2+ Carboxylate Triangles from the Microwave
摘要:
The reaction of M(O2CMe)(2), 4H(2)O (M) Ni, Co) with NaN3 in pyridine/MeOH under microwave irradiation and controlled pressure/temperature leads to the formation of the trimetallic species [M-3-(N-3)(3)(O2CMe)(3)(py)(5)] (M) Ni, 1; Co, 2) in 4 min and in high yields. Both complexes display dominant ferromagnetic interactions and high-spin ground states.

Microwave heating is a new and extremely attractive method for synthesizing polymetallic clusters of paramagnetic transition metal ions. Here we give a brief overview of some of the complexes we have made so far, highlighting the enormous potential of the technique. (c) 2006 Elsevier Ltd. All rights reserved.
