    Description / Table of Contents: New σ-Type-bonded organochromiun compounds are described. They were obtained by reaction of chromium(III)-chloride with o- or p-substituted phenyllithium in diethylether for studying a coordinative influence of the substituents-N(CH3)2,—OCH3,—OLi,—C6H5. The crystalline materials are sensitive to air and moisture and partly pyrophoric. Magnetically the compounds of tervalent chromium point at normal behaviour, that of bivalent chromium at reduced magnetic moment. The compounds are as follows: CrAr3, red (Ar = o-dimethylaminophenyl), CrAr3. LiAr. Ae. reddish brown, CrAr2, yellow, OCrAr. 2, 5LiAr. 1,5Ae, green, (Ar = o-anisyl), CrAr2, yellow (Ar = o-oxyphenyl), CrAr3. 3 LiAr. 3 Ae, yellow (Ar = p-biphenyl).
    Notes: Es werden neue Organochromverbindungen mit σ- Bindungscharakter beschrieben, die in diäthylätherischer Lösung durch Umsetzung von Chrom(III)-chlorid mit o-oder p-substituiertem Lithiumphenyl erhalten wurden, um den koordinativen Einfluß der Substituenten-N(CH3)2,—OCH3,—OLi und—C6H5 zu untersuchen. Die kristallinen Organokomplexe sind luft-und feuchtigkeitsempfindlich und teilweise pyrophor. Bei den Verbindungen des dreiwertigen Chroms ergab sich magnetisch normales Verhalten, bei denen des zweiwertigen Chroms aber ein stark reduziertes magnetisches Moment. Die Komplexe haben die folgenden Zusammensetzungen: CrAr3, rot (Ar = o - Dimethylaminophenyl), CrAr3. 3LiAr3. 3 Ae, orangegelb, CrAr2. LiAr. Ae, schwarzbraun (Ar = p-Dimethylaminophenyl), CrAr3. LiAr. Ae, rotbraun, CrAr2, gelb, OCrAr. 2,5LiAr. 1,5 Ae, grün (Ar = o-Anisyl), CrAr2 gelb (Ar = o-Oxyphenyl), CrAr3. 3 Ae, gelb (Ar =p-Biphenyl).
