| Description
| - Cleavage of a double -halo bridge in complexes [(C5Me4CnF2n+1)RhX2]2 (n = 4, 6; X = Cl, Br) with two-electron monodentate Pdonors like phosphines or phosphites or monodenate N-donors like pyridine-derived heterocyclic amines gave mononuclear Rh(III) complexes of piano-stool type [(C5Me4CnF2n+1)RhX2L] (L = two-electron donor). Crystal structure of [(5-C5Me4C4F9)Rh(PPri3)Cl2] was determined by X-ray diffraction. The compound had a pseudo-tetrahedral ligand arrangement around the Rh atom. The perfluoroalkyl chain was averted from the phosphine ligand but not completely; after projection to the ring plane the P? (ring centroid) ? CF2 angle was around 166°. In contrast to their Cp* analogs, the pyridine complexes were stable in solution at room temperature. Free rotation of triarylphosphine ligands around Rh?P bond and 2-substituted pyridine ligands around Rh?N bond was hindered, giving the values of G++ = 14.8 ? 0.1 kcal mol-1 at 27°C and G++ = 14.9 ?

- Štěpení dvojitého -halo můstku v komplexech [(C5Me4CnF2n+1)RhX2]2 (n = 4, 6; X = Cl, Br) dvouelektronovými monodentátními P-donory jako jsou fosfiny nebo fosfity nebo monodentátními N-donory jako jsou heterocyklické aminy odvozené od pyridinu poskytlo mononukleární Rh(III) komplexy [(C5Me4CnF2n+1)RhX2L] (L = dvouelektronový donor) typu pianová židlička. Krystalová struktura [(5-C5Me4C4F9)Rh(PPri3)Cl2] byla stanovena rentgenovou difrakcí. Sloučenina vykazuje pseudotetraedrické uspořádání ligandů kolem centrálního atomu. Perfluoralkylový řetězec je v poloze odvrácené od fosfinového ligandu, ne však úplně, po projekci do roviny kruhu je úhel P ? centroid kruhu ? CF2 roven 166°. Pyridinové komplexy byly za laboratorní teploty v roztoku stálé, což je v kontrastu s chováním jejich Cp* analogů. Volná rotace triarylfosfinových ligandů kolem Rh-P vazby a 2-substituovaných pyridinových ligandů kolem Rh-N vazby byla bráněna, přičemž analýzou NMR spekter za proměnné teploty byly zjistěny h (cs)
