Kernquadrupolresonanz(KQR)-Spektroskopie an 35 Cl in Komplexverbindungen von Arsentrichlorid, AsCl 3 , mit einigen aromatischen Kohlenwasserstoffen

By measuring the 35 Cl nuclear quadrupole resonance (NQR) spectra it is shown that AsCl 3 , like SbCl 3 , is able to form crystalline complex compounds with aromatic hydrocarbons. Investigation of the freezing-point diagrams reveal the existence of the following compounds: 2 AsCl 3 · C e H 6 ; 2 AsCl 3 · C 10 H 8 ; 2 AsCl 3 · (C 6 H 5 ) 2 CH 2 ; 2 AsCl 3 · p-C 6 H 4 (CH 3 ) 2 ; 2 AsCl 3 · C 6 H 5 C 2 H 5 and AsCl 3 · C 6 H 5 C 2 H 5 . The 35 Cl NQR spectra of these compounds are given and compared with the NQR spectra of the analogous SbCl 3 -complexes.
