Synthesis and properties of trimesitylthallium. A comparison of the trimesitylelement compounds of group 13 Academic Article uri icon

abstract

  • The reaction of TlCl3with MesMgBr (Mes = 2,4,6-Me3C6H2) in THF at 0°C gives trimesitylthallium, TlMes3(2). 2 has been characterized with NMR, IR and MS techniques as well as by an X-ray structure determination. 2 crystallizes isostructural to InMes3(1a). The molecules of 2 are coordinated by the three mesityl substutients in a planar fashion. A new modification of InMes3(1b) could be obtained by recrystallization of InMes3from toluene/n-pentane in the space group C2/c. The literature known modification 1a and the new metallane 2 crystallize in the space group P21/n. The molecules in 1 b possess C2-symmetry. The trimesitylelement compounds EMes3(E = B, Al, Ga, In, Tl) have been compared with each other.
