چکیده
The title compound, [Ti(C5H5)2(C9H11F12NO4P2)], is a four-membered titanacycle obtained from the reaction of Cp2Ti(η(2)-Me3SiC2SiMe3) and CH3N[P(OCH2CF3)2]2 {N,N-bis-[bis-(tri-fluoro-eth-oxy)phosphan-yl]methyl-amine, tfepma}. The Ti(II) atom is coordinated by two cyclo-penta-dienyl (Cp) ligands and the chelating tfepma ligand in a strongly distorted tetra-hedral geometry. The mol-ecule is located on a mirror plane.

In the centrosymmetric title compound, [OsCl(2)(C(18)H(40)O(4)P(2))(2)], the Os(II) atom adopts a trans-OsCl(2)P(4) geometry, arising from its coordination by two chelating diphosphane ligands and two chloride ions. One of the meth-oxy side chains of the ligand is disordered over two orientations in a 0.700 (6):0.300 (6) ratio.

The title dinuclear half-sandwich complex, [CpTi(OCH=CH2)(μ2-N-iPr)]2 (Cp = cyclo-penta-dien-yl; iPr = isopropyl), was ob-tained from the reaction of Cp2TiCl2, n-butyl-lithium and iso-propyl-amine in tetra-hydro-furan. Each Ti(IV) atom is coordinated by one Cp ligand, one vin-yloxy unit and two bridging imido groups in a strongly distorted tetra-hedral geometry. There are two half mol-ecules in...

The asymmetric unit of the title compound, [Fe(2)(C(5)H(5))(2)(C(2)H(8)N(2))(CO)(4)](BF(4))(2), contains two half-cations, each located on a center of symmetry, and two tetra-fluorido-borate anions. The iron atoms adopt a three-legged piano-stool geometry. All amine H atoms are involved in N-H⋯F hydrogen bonds, which consolidate the crystal packing along with weak C-H⋯O and C-H⋯F inter-actions.
