Resumen: To clarify the nature of the Mo[BOND]Carene interaction in terphenyl complexes with quadruple Mo[BOND]Mo bonds, ether adducts of composition [Mo2(Ar′)(I)(O2CR)2(OEt2)] have been prepared and characterized (Ar′=ArXyl2, R=Me; Ar′=ArMes2, R=Me; Ar′=ArXyl2, R=CF3) (Mes=mesityl; Xyl=2,6-Me2C6H3, from now on xylyl) and their reactivity toward different neutral Lewis bases investigated. PMe3, P(OMe)3 and PiPr3 were chosen as P-donors and the reactivity studies complemented with the use of the C-donors CNXyl and CN2C2Me4 (1,3,4,5-tetramethylimidazol-2-ylidene). New compounds of general formula [Mo2(Ar′)(I)(O2CR)2(L)] were obtained, except for the imidazol-2-ylidene ligand that yielded a salt-like compound of composition [Mo2(ArXyl2)(O2CMe)2(CN2C2Me4)2]I. The Mo[BOND]Carene interaction in these complexes has been analyzed with the aid of X-ray data and computational studies. This interaction compensates the coordinative and electronic unsaturation of one of the Mo atoms in the above complexes,...
