摘要：

Cationic dioxorhenium and dioxotechnetium complexes of the composition [MO2(L-1)(4)](+) (L-1 = 1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene) have been prepared from various starting materials and studied spectroscopically and by X-ray crystallography. The metal-carbon distances range from 2.216(4) to 2.232(4) Angstrom indicating mainly sigma-bonding.
