Synthesis, Characterization, and Single-Crystal X-ray Structures of Refractory Metal Compounds as Precursors for the Single-Source Chemical Vapor Deposition of Metal Nitrides

A Versatile Comproportionation Route to Construct Mono‐Imido Trichlorido Complexes of Molybdenum(V) and Tungsten(V)

“…Under the same conditions described above, within two hours a color change from yellow-brown to deep blue (3) or blueish-green ( 4) is observed. [30] Following this procedure, the desired alkyl imido complexes 3 and 4 could be isolated in good yields of 85 and 69 %. Similar to 1 and 2, 1 H-NMR NMR studies in CD 2 Cl 2 show the presences of strongly paramagnetically shifted resonances, which cannot be further analyzed.…”

Put a Ring on It: Improving the Thermal Stability of Molybdenum Imides through Ligand Rigidification

“…Therefore, we were curious if we could isolate a model of this metastable intermediate for further investigation. We have recently reported a chromium analogue of these compounds, ( t BuN) 2 CrCl 2 ·dad (dad = 1,4-di tert -butyl-1,3-diazabuta-diene), that was isolated and characterized as a κ 1 -complex in the solid-state, but we have not observed such complexes for molybdenum.…”
