When they come into contact with air, coordination compounds can often change their appearance. For instance, the colour of the compound can change as transparent crystals become opaque microcrystalline solids. This visible transformation of the comp

Starting from Mo(N2)2(depe)2 (1), the nitrido complex Mo(N)(N3)(depe)2 (2) was obtained by the reaction of 1 with Me3SiN3. Subsequent reaction of 2 with HCl in CH3OH afforded the cationic imido chloride 3, which could be converted into the nitrido ch
