The oxidation of tantalum with ammonium chloride as an example of a novel route to early transitional metal–nitrogen cluster compounds. Synthesis and crystal structure of (NH4)6[Ta5(NH)4Cl17]
Abstract
The oxidation of tantalum metal with ammonium chloride leads to dark-green single crystals of (NH4)6[Ta5(NH)4Cl17], a new imido-bridged tantalum-cluster compound with the [Ta5(NH)4Cl17]6– anion.
