Poly[μ(3)-chlorido-μ(2)-chloridodichlorido(μ-dimethyl sulfoxide-κO:S)(dimethyl
Abstract:
The title complex, [NaRuCl(4)(C(4)H(4)N(2))(C(2)H(6)OS)(2)](n), is the sodium salt of monoanionic octa-hedral [Ru(III)Cl(4)(pyrimidine)(DMSO)](-) in which the sulfur-bound dimethyl sulfoxide (DMSO) and pyrimidine ligand are oriented trans to one another on the Ru(III) atom. The average of the four Ru-Cl bond lengths is 2.355 (15) Å, and the Ru-S and Ru-N bond lengths are 2.2853 (3) and 2.1165 (11) Å, respectively. The complex forms a chain, with a six-coordinate sodium ion bridging the ruthenium(III) units. The sodium cation is coordinated by cis-chloride ligands on ruthenium [Na-Cl = 2.9576 (7) and 2.6988 (7) Å], chloride and DMSO ligands from the ruthenium complexes related by inversion [Na-Cl and Na-O = 2.8888 (7) and 2.2623 (12) Å, respectively], a nitro-gen ligand from the pyrimidine of the tetrachlorido-ruthenium(III) complex related by the twofold rotation axis [Na-N = 2.5224 (14) Å] and an oxygen-bound DMSO [Na-O = 2.3165 (12) Å].

Nucleophilic Substitution Reactions
In 1896, the German chemist Paul Walden discovered that he could interconvert pure enantiomeric (+) and (-) malic acids through a series of reactions. This conversion suggested the involvement of optical inversion during the substitution reaction. Further, in 1930, Sir Christopher Ingold described for the first time two different forms of nucleophilic substitution reactions, which are known as SN1 (nucleophilic substitution unimolecular) and SN2 (nucleophilic substitution...
