The organoelement subhalides R 2 Ga 2 I 2 ( 5 ) and R 3 In 3 I 2 [ 6 ; R = C(SiMe 3 ) 3 ] reacted with silver benzoate AgOOCC 6 H 5 to yield the dicarboxylato dielement compounds R 2 E 2 (µ‐OOCC 6 H 5 ‐ O , O ′) 2 ( 7 , E = Ga; 8 , E = In). Both compounds possess E−E single bonds bridged by the chelating carboxylato ligands. The chelating groups are arranged perpendicular to one another. Owing to the small bite of the carboxylato group very short E−E bond lengths of 240.5 pm (Ga−Ga) and 265.4 pm (In−In) were observed. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
