Synthese und Kristallstruktur von [(C₆Et₆)(C₆H₅Me)GaGaCl₄]· 1/2 (C₆Et₆): Ein gemischter Bis(η⁶-aren)gallium(I)-Komplex / Synthesis and Crystal Structure of [(C₆Et₆)(C₆H₅Me)GaGaCl₄] · 1/2 (C₆Et₆): A Mixed Bis(η⁶-arene)gallium(I) Complex

Abstract

Crystals obtained from solutions of hexaethylbenzene and anhydrous Ga[GaCl 4 ] in toluene on cooling have the stoichiometry [(C 6 Et 6 )(C 6 H 5 Me)GaGaCl 4 ] · 1/2 C 6 Et 6 . a = 9.760(1), b = 21.447(2), c = 17.754(2) Å. β = 95.47(1)°; monoclinic. space group P2 1 /n. Z = 4. Each Ga(I) center is η 6 -bonded to one molecule of hexaethylbenzene and to one molecule of toluene. The two rings form an angle of 38,8°. The remaining crystal hexaethylbenzene is situated between two complex units, which are related by an inversion center located in the center of the ring.
