摘要

We found that the reaction of a polymeric cobalt(II) complex, which was prepared by melting cobalt(II) acetate tetrahydrate with trimethylacetic acid, with 3,5-dimethylpyrazole (PirH) (Co(OOCBu~t)_2 : PirH = 1:2) in refluxing o-xylene afforded the violet Co_2(mu-Pir)_2(OOCCMe_3)_2(PirH)_2 complex (1, 53% yield).
