“…to be largely determined by the packing considerations of and interactions between the pyridine moieties {e.g., an intermolecular contact of 3.566 (8) Å is observed between N(101) and C(104) in the structure of [Ru(MeCO 2 )(CO) 2 (py)] 2 }. The introduction of a phenyl substituent in the benzoate/pyridine complex causes a perturbation of the long range chain-like order observed in [Ru(MeCO 2 )-(CO) 2 (py)] 2 by enabling association of pairs of the dimer through π-stacking of these groups.…”

“…An alternative but less extensively employed procedure has entailed the reduction of µ 3 -oxo-triruthenium() acetate. 8 The process is summarised in Scheme 2. Solvated with dimethylformamide, this complex exists as a monovalent cation.…”

“…Reduction with H 2 afforded a brown residue, which was reacted with various unidentate donors in purified deoxygenated methanol to afford the complexes [Ru(RCO 2 )(CO) 2 (L)] 2 . 8 In addition to difficulties attributable to the air-sensitive nature of some intermediates, reported yields were low and mixtures of products obtained. 8 We report here a benign and efficient procedure for the synthesis of di-µ-carboxylatotetracarbonyldiruthenium() complexes.…”

“…8 In addition to difficulties attributable to the air-sensitive nature of some intermediates, reported yields were low and mixtures of products obtained. 8 We report here a benign and efficient procedure for the synthesis of di-µ-carboxylatotetracarbonyldiruthenium() complexes. This novel synthetic route is based upon the facile reduction of the readily prepared dicarbonyldichlororuthenium() polymer 9 in methanolic suspension in the presence of carboxylates.…”

Polymeric dicarbonyldichlororuthenium() [Ru(CO) 2 Cl 2 ] n is reduced by reaction with carboxylate salts (RCO 2 Ϫ Na ϩ ) in alcoholic suspension. Dimeric ruthenium() "sawhorse" complexes [Ru(RCO 2 )(CO) 2 L] 2 (R = Me, Et, Bu t , Ph) are formed on the addition of a monodentate ligand, L [L = pyridine (py) or 3-methylpyridine (Mepy)]. Characterisation of [Ru(MeCO 2 )(CO) 2 (py)] 2 , [Ru(MeCO 2 )(CO) 2 (Mepy)] 2 , [Ru(EtCO 2 )(CO) 2 (py)] 2 , [Ru(Bu t CO 2 )(CO) 2 (py)] 2 and [Ru(PhCO 2 )(CO) 2 (py)] 2 by IR and 1 H NMR spectroscopy is reported. Structural elucidation by single crystal X-ray diffraction was achieved in each case revealing a dicarboxylate bridged diruthenium() complex with cisoid carbonyls and pyridine ligands approximately collinear with the ruthenium-ruthenium bond. Scheme 2 A further synthetic procedure affording [Ru(MeCO 2 )-(CO) 2 (L)] 2 .

“…The useful RuPc(dmso), precursor complex can be obtained after a procedure involving refluxing "RuPc" in dmso; a similar procedure using dmf yields the monocarbonyl RuPc(CO)(dmf) formed presumably by decarbonylation of the amide, a process not uncommon for ruthenium (16,17).…”

. Can. J. Chem. 58, 1125Chem. 58, (1980. Ruthenium(I1) phthalocyanine complexes of the type RuPcL, (PC = the phthalocyaninato dianion. L = various pyridines, imidazole, dimethylformamide, dimethylsulfoxide, and acetonitrile) may be prepared generally in solution by photolysis of RuPc(C0)L' complexes in the presence of excess L (L' may be the same as L or may be a different ligand), and in some cases a s solids by extraction of crude RuPc with L. The solid RuPc(C0)L monocarbonyls can be formed from reaction of the RuPcL, complexes with carbon monoxide, as well as via an extraction procedure using L with crude RuPc(C0) formed from Ru,(CO),, and phthalocyanine.Chemical or electrochemical oxidation of the RuPcL' or monocarbonyl complexes generates a cationic ruthenium(I1) phthalocyanine radical species and not ruthenium(III), as evidenced by esr and visible spectroscopy.
