Crystal-Field Properties of Pentalene Ligands in Erbium(III) Sandwich Complexes
{{output}}
The influence of pentalene ligands on the crystal-field properties of erbium-(III) has been examined using the monometallic complexes [Er-(η8-Pn†)2]- (1) and [(η8-Pn†)-Er-(η8-COT)]- (2) (Pn† = [1,4-( i Pr3Si)2C8H4]2-, COT = [C8H8]2-), which were synthesi... ...
