| Abstract: | Reactions of the Gallium‐containing Heterocycle Me2Ga{HNC(Me)}2CCN] The reaction of Me2Ga{HNC(Me)}2CCN] ( 1 ) with fac‐Mo(CO)3(MeCN)3] leads after addition of TMEDA to the molybdenum complex fac‐Mo(CO)3( 1 )(TMEDA)] ( 2 ). Under identical reaction conditions with fac‐W(CO)3(MeCN)3] only the tetracarbonyle complex W(CO)4(TMEDA)] ( 3 ) could be isolated. Treatment of dilithiated 1 with Me2SiCl2 or InCl3 initiate a fragmentation of the skeleton in 1 . Obtained were the salt Me2Ga(TMEDA)]Me2GaCl2] ( 4 ) and the indium complex Me2InCl(TMEDA)] ( 5 ), respectively. 2 — 5 were investigated by spectroscopical and spectrometrical methods as well as by X‐ray structure determinations. According to these 1 occupies a facial site in 2 by donation of the N‐Atom from the NC group in 1 . The molecules 2 are forming a network of hydrogen bonds. In 3 , the TMEDA ligand acts as an intramolecular chelate ligand. In the salt 4 , the cation as well as the anion are coordinated in a distorted tetrahedral environment, while in 5 a distorded trigonal‐bipyramidal coordination‐sphere is present, leading to a elongated In1‐Cl1 distance of 261.74(9) pm. |
