Tellurated azobenzenes: The crystal and molecular structure of (2-phenylazophenyl-C,7N′)tellurium(IV) trichloride

摘要: Abstract The preparation of the title compound via a trans -metallation route has been reinvestigated, and also its formation by direct telluration azobenzene at 135–150°C demonstrated. 13 C NMR data for tellurated mercurated are compared. Reduction with excess hydrazine affords new ditelluride (C 12 H 9 N 2 ) Te . crystal structure (2-phenylazophenyl- , ′)tellurium(IV) trichloride determined. coordination about is octahedral vacant equatorial position, two Cl atoms apical, third atom bidentate organic ligand equatorial. essentially monomeric, there no significant interactions between in neighbouring molecules.
