Abstract Reaction of a 1:1 mixture of Sm[N(SiMe3)2]3 and Ti(O-i-Pr)4 with three equivalents of 2,6-di-iso-propylphenol, followed by crystallization from hexane/THF, leads to isolation of the tetranuclear samarium alkoxide Sm4(μ3-O-i-Pr)3(μ2-O-i-Pr)4(O-i-Pr)2(O-2,6-i-Pr2C6H3)3(THF) (1), in addition to the dimeric titanium alkoxide [Ti(O-i-Pr)2(O-2,6-i-Pr2C6H3)(μ-O-i-Pr)]2 (2). 1 crystallizes in the space group $$P\bar 1$$ while 2 crystallizes in space group P21/c. Cell parameters for 1: a = 15.928(6), b = 17.677(7), c = 18.99(1) Å, α = 113.24(3), β = 94.99(4), γ = 109.59(2)°, V = 4477(4) Å3, D calc = 1.350 Mg/m3, and Z = 2. Cell parameters for 2: a = 25.336(2), b = 12.082(1), c = 15.570(2) Å, β = 96.510(8)°, V = 4735.4(8) Å3, D calc = 1.129 mg/m3, and Z = 4.
