“…Various Tp‘Mo(CO) 2 (NO) and Tp‘Mo(NO)X 2 (Tp‘ = Tp p -MeOPh , Tp i Pr,Me , or Tp* R ; X = Cl, I, OMe, or OEt) complexes and related species having even bulkier Tp‘ ligands have been prepared and structurally characterized. In addition, the solid-state molecular structures of L 3 Mo(CO) 2 (NO) compounds in which L 3 is a uninegative nitrogen-tripod ligand derived from heterocyclic compounds including 1- H -pyrazole and 1- H -1,2,4-triazole have been determined . The molybdenum atom remains in an octahedral coordination environment in all these complexes.…”

“…291 In related work, the [Ru(bipy) 3 ] 2+ chromophore has been linked at the periphery to the electron-accepting Tp*M(NO)Cl fragments, and this results in complete quenching of the of the dπ(Ru)π*(bipy) metal-to-ligand charge-transfer excited state at room temperature. 292 Various Tp′Mo(CO) 2 (NO) and Tp′Mo(NO)X 2 (Tp′ ) Tp p-MeOPh , Tp iPr,Me , or Tp* R ; X ) Cl, I, OMe, or OEt) complexes and related species having even bulkier Tp′ ligands 293 have been prepared and structurally characterized. [294][295][296] In addition, the solid-state molecular structures of L 3 Mo(CO) 2 (NO) compounds in which L 3 is a uninegative nitrogen-tripod ligand derived from heterocyclic compounds including 1-Hpyrazole and 1-H-1,2,4-triazole have been determined.…”

“…The scarce examples described of these ligands are almost restricted to those presenting methyl or hydrogen groups on positions 3 and/or 5 of the pyrazole rings due to the difficulty associated with the thermal introduction of the fourth heterocycle. 3b , 19c , 19g , 22 Table 3 shows the remarkable yields obtained for a variety of Tkp x Na ( 4a – f Na ) with highly encumbering substituents. Alkaline salts of these ligands are a common entrance to other metal complexes through metal exchange.…”
