“…The reactions were conducted under a atmosphere of high purity nitrogen using standard Schlenk techniques and hexanedried over sodium metal. Tris(4-methoxyphenyl)arsine (Blicke et al, 1938) and bis(diphenylarsino)methanedecacarbonyltriruthenium(0) (Bruce et al, 1983) were prepared by reported procedures. The title compound was obtained by refluxing equimolar quantities of Ru 3 (CO) 10 (µ-Ph 2 AsCH 2 AsPh 2 ) (105.5 mg, 0.1 mmol) and tris(4-methoxyphenyl)arsine (39.63 mg, 0.1 mmol) in hexane under nitrogen atmosphere.…”

The asymmetric unit of the title triangulo-triruthenium compound, 2[Ru3(C25H22As2)(C21H21AsO3)(CO)9]·CH2Cl2, contains one triangulo-triruthenium complex molecule and one half of the dichloromethane solvent. The dichloromethane solvent lies across a crystallographic inversion center leading to the molecule being disordered over two positions of equal occupancy. The bis(diphenylarsino)methane ligand bridges an Ru—Ru bond and the monodentate arsine ligand bonds to the third Ru atom. Both the arsine ligands are equatorial with respect to the Ru3 triangle. In addition, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The trimethoxyphenylarsino benzene rings make dihedral angles of 83.01 (8), 65.81 (8) and 76.20 (8)° with each other. The dihedral angles between the two benzene rings are 82.69 (9) and 78.83 (9)° for the two diphenylarsino groups. In the crystal packing, the molecules are stacked along the a axis and weak intermolecular C—H⋯π interactions stabilize the crystal structure.

The asymmetric unit of the title triangulo-triruthenium compound, 2[Ru3(C21H21AsO3)(C25H22P2)(CO)9]·CH2Cl2, contains one triangulo-triruthenium complex molecule and one half-molecule of the dichloromethane solvent. The dichloromethane solvent lies across a crystallographic inversion center leading to the molecule being disordered over two positions of equal occupancy. The bis(diphenylphosphino)methane ligand bridges an Ru—Ru bond and the monodentate arsine ligand bonds to the third Ru atom. Both the arsine and phosphine ligands are equatorial with respect to the Ru3 triangle. In addition, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The three arsine-substituted benzene rings make dihedral angles of 82.00 (6), 76.67 (7) and 66.09 (6)° with each other. The dihedral angles between the two benzene rings are 80.12 (8) and 78.34 (7)° for the two diphenylphosphino groups. In the crystal packing, the molecules are linked together into chains down the b axis via intermolecular C—H⋯O hydrogen bonds. An intermolecular C—H⋯O hydrogen bond and weak intermolecular C—H⋯π interactions further stabilize the crystal structure.

The structure of organic compounds of arsenic is considered. Data are presented on the configurational stability and the energy of the inversion barrier in asymmetric arsines. The methods of synthesis of tertiary asymmetric arsenic compounds are surveyed. The results of the separation of asymmetric arsines into optically active isomers and the mechanisms of their transformation as well as the influence of substituents in the benzene ring on the optical activity are described. An analogy is drawn between the stereochemistries of organophosphorus and organoarsenic compounds. The bibliography includes 220 references. CONTENTS
