Abstract

Reaction of LK (L = HC(CMeNAr)₂, Ar = 2,6-iPr₂C ₆H₃) and MnCl₂(THF)_1.5 in THF unexpectedly resulted in the formation of the trinuclear complex LMn(μ-Cl)₂Mn(THF)₂(μ-Cl)₂MnL (1) in good yield. The substitution reactions of 1 with C₃H₅MgCl and PhCCLi, respectively, provided the monomeric LMnC₃H₅CTHF) (2) and the dimeric [LMn(μ-CCPh)]₂ (3) in moderate yield. Complexes 1-3 were characterized by single-crystal X-ray structural analysis. The structures show that compound 1 contains an ideal planar Mn ₃Cl₄ core and a linear Mn₃ trimer, the allyl ligand in 2 is in an η¹ mode, and there is π-interaction between the triple bond and the metal center in 3.
