Synthesis And Characterization Of Group 5 Metal Complexes Containing Pyrazolate, Amidate, And Related Ligands As Potential Precursors For Thin Film Growth By Atomic Layer Deposition
… niobium(IV) and tantalum(IV) complexes from pyrazolate, amidate, and α-iminoketone ligand systems. Pyrazolate compounds undergo reductive N-N bond cleavage on Nb(IV) and Ta(IV) metal centers and afford six membered metallacycles that are analogous to metallapyrimidines and …

Calorimetric studies of small-molecule adsorption to carbon nanotubes
… adsorption of a in-basic metalloaromatic gold pyrazolate trimer, [Au(3,5- Et2Pz)] 3, to SWCNTs in DMF is accompanied by a large negative enthalpy change, while the structurally-related it-acidic macrocycle, [Hg(C 6F4)]3, does not have a large enthalpy of adsorption. This result agrees with …
