Synthesis, Structure and Application of Intramolecularly‐Coordinated Gallium Chalcogenides: Suitable Single‐Source precursors for Ga x Se y Materials
Studies have been focused on the synthesis of N→Ga‐coordinated organogallium selenides and tellurides [L 1 Ga(μ‐Se)] 2 ( 1 ), [L 2 Ga(μ‐Se)] 2 ( 2 ) and [L 1 Ga(μ‐Te)] 2 ( 3 ), respectively, containing either N,C,N‐ or C,N‐chelating ligands L 1, 2 (L 1 is {2,6‐(Me 2 NCH 2 ) 2 C 6 H 3 } − and L 2 is...
