Acetate and acetamide complexes of [Ni(Me4[12]aneN4)]PF6: a tale of two ligands

Although there are many examples of acetate complexes, acetamide complexes are virtually unknown. A side-by-side comparison in (acetato-κ2O,O′)(1,4,7,10-tetramethyl-1,4,7,10-tetraazacyclododecane-κ4N)nickel(II) hexafluoridophosphate, [Ni(C2H3O2)(C12H28N4)]PF6, (1), and (acetamidato-κ2O,O′)(1,4,7,10-tetramethyl-1,4,7,10-tetraazacyclododecane-κ4N)nickel(II) hexafluoridophosphate, [Ni(C2H4NO)(C12H28N4)]PF6, (2), shows the steric equivalence between these two ligands, suggesting that acetamide could be considered as a viable acetate replacement for electronic tuning.
