Synthesis and Spectroscopic Characterisation of a New Class of Heterobimetallic Homoleptic Diethanolaminate Complexes of Niobium(V) and Tantalum(V)

“…9,10 Recently, we have developed a novel route for the synthesis of heterobimetallic alkoxide coordination complexes 11 utilising the higher reactivity of the hydroxy functionality in homometallic complexes derived from polyols such as glycols, di-and triethanolamines. 11 This strategy has been successful in the synthesis of novel heterobimetallic glycolate-, 12,16 diethanolaminate- [17][18][19][20] and triethanolaminate- 13,21,22 isopropoxide complexes. Due to the presence of isopropoxy groups, these types of complexes show a strong propensity for hydrolysis 3,11 even in the presence of only traces of moisture.…”
