Chlorido(η5‐cyclopentadienyl)bis(dimethylamido)titanium, [TiCl(η5‐C5H5)(NMe2)2]

The title complex, [Ti(C₅H₅)(C₂H₆N)₂Cl], exhibits two nearly planar dimethylamide groups oriented approximately perpendicular to each other. The Ti→cyclopentadienyl centroid vector lies nearly in the plane of one of the dimethylamide groups. Long‐range contacts between Ti—Cl and cyclopentadienyl H—C groups give rise to geometric ordering in the extended solid.     

[μ‐1κ2O,O′:2(η5)‐Cyclopentadienylcarboxylato][2(η5)‐diphenylphosphinocyclopentadienyl]bis[1,1(η5)‐tetramethylcyclopentadienyl]iron(II)titanium(III)

Reacting stoichiometric amounts of 1‐(diphenylphosphino)ferrocene­carboxylic acid and [Ti(η⁵‐C₅HMe₄)₂(η²‐Me₃SiC[triple‐bond]CSiMe₃)] produced the title carboxyl­atotitanocene complex, [{μ‐1κ²O,O′:2(η⁵)‐C₅H₄CO₂}{2(η⁵)‐C₅H₄P(C₆H₅)₂}{1(η⁵)‐C₅H(CH₃)₄}₂Fe^IITi^III] or [FeTi(C₉H₁₃)₂(C₆H₄O₂)(C₁₇H₁₄P)]. The angle subtended by the Ti/O/O′ plane, where O and O′ are the donor atoms of the κ²‐carboxy­late group, and the plane of the carboxyl‐substituted ferrocene cyclo­penta­dienyl is 24.93 (6)°.
