摘要Reaction of Ce(O-t-Bu)2(NO3)2 and sodium guanidinate GuaNa (Gua- = TMS2NC(NC6H11)2-) in THF affords the first guanidinate Ce(IV) complex of Ce2(O-t-Bu)7(Gua')(1,Gua'-= (C6H11NH)C(NC6H11)(NH)-). It crystallizes in monoclinic, space group P21/nwith a = 15.2937(14), b = 17.8409(16), c = 19.0454(16) Å, β = 97.713(2)°, V = 5149.6(8) Å3, Z = 4, Mr= 1014.38, Dc= 1.308 g/cm3, μ = 1.787 mm-1, F(000) = 2104, S = 1.015, R = 0.0451 and wR = 0.0901 (I > 2σ(I)). In the reaction the cleavage of TMS-N bonds happened unexpectedly.
