摘要 Reaction of(NH4)2 Ce(NO3)6 first with NaOtBu in a 1:6 molar ratio in THF, then with an equivalent of 2-bis(salicylidieneamino)methylphenol(H3 salmp) affords the(salmp)2 Ce2-(O)Na4(OtBu)4(THF)4 ·2C6 H6 complex. It crystallizes in monoclinic, space group C2/c with a = 16.5218(14), b = 23.992(2), c = 21.9454(18), β = 97.470(1)°, V = 8625.1(12)3, Z = 4, Mr = 1811.96, Dc = 1.395 g/cm3, μ = 1.126 mm-1, F(000) = 3736, S = 1.061, R = 0.0405 and wR = 0.0932(I 〉 2σ(I)).
