“…Initial coordinates for the non-H atoms were those obtained in the previous determination (Mills & Nice, 1967). These were refined to near convergence with anisotropic displacement parameters for all non-H atoms by a full-matrix least-squares method and all H atoms were located from the resulting Ap map.…”

“…From the unit cell obtained it was clear that this was not the case and a search of the Cambridge Structural Database showed that the crystals were in fact [Cp2Ru2(CO)4], (1), which is a possible side product in the synthesis of CpRuCI-(CO)2, and was evidently present as a contaminant in the sample of the dicarbonyl used to prepare the 'metalloligand'. Noting that the original structure determination for (1) (Mills & Nice, 1967) was of low…”

“…2) reveals that the complex has a trans conformation with two bridging carbonyl ligands. Similar to the cyclopentadienyl analog trans-[g 5 -CpRu(CO)(l-CO)] 2 [17] (where Cp = cyclopentadienyl ligand), both the structures are trans form and have Table 2 Selected bond distances (Å ) and angles (°) for 3 [20]. This distance is comparable to those found in other substituted cyclopentadienyl ruthenium dicarbonyl dimers [21].…”

“…The Ru-Ru bond distance is 0.2738(2) nm. The Ru-Ru Bond distance is slightly longer than that in trans-[g 5 -CpRu(CO)(l-CO)] 2 [2.735(2) Å ][17], but slightly shorter than that in trans-[g 5 -CpMe 4 i hexRu(CO)(l-CO)…”

Reactions of the pyridyl side-chain-functionalized cyclopentadiene [C 5 H 5 CR 2 (CH 2 C 5 H 4 N)] [R 2 = Et 2 (1), (CH 2 ) 4 (2)] with Ru 3 (CO) 12 in refluxing xylene gave the new intramolecular C-H activated trinuclear product [l-(C 5 H 3 N)CH 2 C(C 2 H 5 ) 2 (C 5 H 4 )Ru(CO)] 2 Ru(CO) 2 (3) and the normal dinuclear metal complex [(C 5 H 4 N)CH 2 C(CH 2 ) 4 -(C 5 H 4 )Ru(CO)] 2 (l-CO) 2 (4). The structures of the trinuclear complex 3 and dinuclear complex 4 were characterized by elemental analysis, IR spectra, 1 H-NMR and X-ray diffraction.

The structures of all possible isomeric forms of the [M(h 5 -C 5 H 5 )(CO) 2 ] 2 complexes (M=Fe, Ru) are calculated with the use of the DFT method. The results indicate that both dimers can occur in three stable forms: bridged trans and cis and non-bridged trans. Contrary to the previous reports, the cis non-bridged form turns out to be an unstable transition state. Instead, an additional stable structure, a gauche non-bridged one, is found but only in the case of the Ru compound. Without any outer-sphere interaction the trans-bridged form is of the lowest energy for both dimers. The results are compared with the experimental data. Strong impact of the medium on the stability of the individual structures in solution is emphasized. The electronic spectra of all stable forms, calculated using TDDFT method, reproduce well spectral properties of both complexes. Moreover, they are useful in interpreting the medium effect and photochemical behaviour. The photoreactivity is briefly reviewed pointing at analogies and differences between the Fe and Ru complexes.
