cis-Dicarbonyl-cis-dichlorido-trans-bis­(triphenyl­phosphine-κP)iridium(III) tetra­fluorido­borate, formed by reaction of (cyclo­octa-1,5-diene)bis­(triphenyl­phosphine)iridium tetrafluoridoborate with carbonyl fluoride in dichloro­methane solution

The reaction between carbonyl fluoride and [Ir(COD)(PPh₃)₂]BF₄ (COD is cyclo­octa-1,5-diene) in dichloro­methane solution affords the novel title iridium salt, [IrCl₂(C₁₈H₁₅P)₂(CO)₂]BF₄. The cation lies across a twofold rotation axis in the space group P2₁2₁2 and its structure confirms the presence in a cis relationship of two metal-bound chlorides, while the phosphine ligands occupy a trans pair of sites. The anion also lies across a twofold rotation axis, and the F atoms are disordered over two sets of sites.

Bis[1,2-bis­(diphenyl­phosphino)ethane-κ²P,P′]difluoridoruthenium(II) trichloro­methane disolvate

In the crystal structure of the title compound, [RuF₂(C₂₆H₂₄P₂)₂]·2CHCl₃, the Ru atom lies on a centre of symmetry with a trans arrangement of the F atoms. A H...F contact (2.249 Å) suggests weak intra­molecular hydrogen bonding. The solvent mol­ecules exhibit hydrogen bonding with the F atoms (H...F = 1.91 Å).
