New benzyl complexes of the lanthanides. Synthesis and crystal structures of [(C5Me5)2Y(CH2C6H 5)(thf)], [(C5Me5)2Sm(CH2C6H 5)2K(thf)2]∞

YBr3 reacts with potassium benzyl and [K(C5Me5)] in THF to give KBr and the monobenzyl compound [(C5Me5)2 · Y(CH2C6H5)(thf)] 1. The analogous reaction with SmBr3 in THF leads to the polymeric product [(C5Me5)2Sm(CH2C6H 5)2 · K(thf)2]∞ 2, with GdBr3 to [(C5Me5)Gd(CH2C6H5) 2(thf)] 3. The structures of 1-3 were determined by X-ray single crystal structure analysis: 1: Space group P1, Z = 2, a = 851.2(4) pm, b = 952.7(4) pm, c = 1858.6(8) pm, α = 79.90(4)°, β = 77.35(4)°, γ = 73.30(3)°. 2: Space group P1, Z = 2, a = 903.3(2)pm, b = 1375.9(3)pm, c = 1801.1(4) pm, α = 100.92(3)°, β = 100.77°, γ = 98.25(3)°. 3: Space group P21/n, Z = 8, a = 1458.2(5) pm, b = 927.8(3) pm, c = 3792.9(15) pm, β = 96.83(3)°. ?
