Bis(N,N-di-tert-butyl-1,4-diaza-1,3-butadienyl)cobalt is one of the Cobalt N,N’-alkylamidinates with various substitute radicals. These are volatile, thermally stable, having high reactivity at low deposition temperatures compounds. The variation of melting points of different cobalt amidinates was explained by the total number of flexible joints in the alkyl substituents. The presence of more flexible ethyl and n-butyl groups tends to lower the melting points, while higher melting amidinates possess more rigid tert-butyl and isopropyl substituents. See link below
