Abstract

Reaction of [{Sm(C5Me5)(μ-OAr)}2] (Ar = 2,6-(t-Bu)2-4-MeC6H2) or [Sm(C5Me5)2(thf)2] with 1 equiv of [{Ir(C5Me5)Cl(μ-Cl)}2] in THF gave the “ate” complex [Ir(C5Me5)2][Sm(C5Me5)2Cl2] (1) as orange-red crystals in 60—74% yields (based on Sm). Complex 1 represents the first example of a structurally characterized metallocenium lanthanocene dihalide complex. Crystal data for 1: monoclinic, space group P21/m (No. 11), a = 9.781(4), b = 14.956(4), c = 13.842(5) Å, β = 93.38(3)°, V = 2021(1) Å3, Z = 2, Dc = 1.57 g cm−3, R = 7.75%, RW = 9.23%, GOF = 1.12.
