Synthesis and Structure of a Titanocene-ferrocenyl Complex

A titanocene-ferrocenyl complex, (5-ferrocenyl-2-hydroxybenzenecarboxylato-O,O')-bis(methylcyclopentadienyl)titanium(Ⅳ) 4, and an unexpected ionic complex, [C7H6NO3]-[(C5H5)Fe(C5H4)SO3]-H2O 3 were synthesized and characterized by IR, 1H NMR and elemental analysis. Compound 3 is of triclinic, space group P1 with a=5.954(2), b=13.208(5), c =13.252(5) A,α=60.993(7),β=84.342(8),γ=86.933(8)°,Z=2,V=906.8(6)A3,Dc=1.601g/cm3,μ(MoKa)=0.987mm-1,F(000)=452, the final R=0.0647 and wR=0.1333 for 2311 observed reflections (I> 2σ(I)). Compound 4 belongs to the monoclinic system, space group P2l/c with a = 14.3310(9), b = 12.5065(8), c = 12.9406(10) A, β = 95.101(4)°, Z = 4, V = 2310.2(3) A3,Dc= 1.513 g/cm3,°(MoKa) = 1.004 mm-1, F(000) = 1088, the final R = 0.0461 and wR =0.1048for 2112 observed reflections (I > 2σ(I)).
