Tris[4-(methylsulfanyl)phenyl]arsine

Abstract

In the title compound, C21H21AsS3, the three benzene rings make dihedral angles of 88.41 (10), 87.75 (9) and 74.74 (10)° with each other. The methyl­sulfanyl groups are roughly coplanar with their attached benzene rings [C—S—C—C torsion angles = −7.6 (2), 11.2 (2) and 4.1 (2)°]. In the crystal, weak C—H⋯π inter­actions link the mol­ecules.

Bis{[μ-bis(diphenylarsino)methane-1:2κ2As:As′]nonacarbonyl-1κ3C,2κ3C,3κ3C-[tris(4-methoxyphenyl)arsine-3κAs]-triangulo-triruthenium(0)} dichloromethane solvate

“…The dichloromethane solvent lies across a crystallographic inversion center leading to the molecule being disordered over two positions of equal occupancy. The bond lengths and angles of title compound are comparable to those found in related structure (Shawkataly et al, 2009(Shawkataly et al, ,2010. The bis(diphenylarsino)methane ligand bridges the Ru1-Ru2 bond and the monodentate arsine ligand bonds to the Ru3 atom.…”

“…As part of our study on the substitution of transition metal-carbonyl clusters with mixed-ligand complexes, we have published several structures of triangulo-triruthenium-carbonyl clusters containing mixed P/As and P/Sb ligands (Shawkataly et al, 1998(Shawkataly et al, , 2004(Shawkataly et al, , 2009(Shawkataly et al, ,2010. Herein, we report the synthesis and structure of title compound.…”
