“…The interest in coordination complexes of ruthenium stems from their versatile electron-and energy-transfer properties [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. As a result these complexes exhibit a wide range of reactivities.…”

A series of new binuclear Ru(III) complexes of the type {[RuX 3 (EPh 3 )] 2 (bis-b-dk)} [X = Cl/Br; E = P/ As bis-b-dk = bis(b-diketone)] have been prepared by reacting [RuCl 3 (PPh 3 ) 3 ], [RuCl 3 (AsPh 3 ) 3 ], [RuBr 3 (PPh 3 ) 3 ],[RuBr 3 (AsPh 3 ) 3 ] with bis(b-diketones) in a 2:1 molar ratio in benzene. These complexes have been characterized by physico-chemical and spectroscopic methods. The redox property of the complexes were studied by cyclic voltammetric technique. The complexes were found to be effective catalysts for the aryl-aryl coupling and oxidation of benzyl alcohol, cyclohexanol, propan-1-ol and 2-methylpropanol to benzaldehyde, cyclohexanone, propionaldehyde and 2-methylpropionaldehyde, respectively, using molecular oxygen as primary oxidant. All the complexes have been screened for their antibacterial and antifungal activities.

“…Especially, their ability to release NO is of considerable importance. This reaction may take place thermally or photochemically [4][5][6]. Since photoreactions can be controlled much better than thermal reactions the light-induced ejection of NO from nitrosyl complexes could be utilized for medical purposes.…”

“…In addition, NO þ has been shown to act as CT acceptor for MLCT [8] transitions, but there is no reason while it should not also act as CT acceptor for LLCT transitions. The existence of such LLCT (to NO þ ) transitions in complexes including [Fe II (CN) 5 (NO)] 2 [5] and (g-C 5 H 5 )Ni 0 (NO) [25] has been previously considered.…”

“…Recently photochemistry of I was reviewed in details by Bitterwolf [2], whereas behaviour of its ruthenium analogue was described to a lesser extent.At the same time the possibility of using [CpM(CO) 2 ] 2 complexes as versatile systems was considered with the ligand and medium controlled photochemistry [1]. Here we intend to emphasize some points of I and II photochemistry, which are closely associated with their structures.…”

“…The theoretical interest in the [M(h 5 -C 5 H 5 )(CO) 2 ] 2 dimers concerns mostly their versatile structures which entail varied thermal and photochemical behaviour [1,2]. The versatility is reflected by the structural changes accompanying crystal dissolution or a change of solvent [2].…”

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.
