[ScCl2{N(SiMe3)2}(THF)2] als Vorläufer für die Synthese von Scandiumnitrid
摘要:
[ScCl2{N(SiMe3)(2)}(THF)(2)] (1) has been prepared by the reaction of [ScCl3(THF)(3)] with the trisamide SC[N(SiMe3)(2)](3) in tetrahydrofurane solution forming colourless moisture sensitive crystals, which were characterized by a crystal structure determination. Space group P (1) over bar, Z = 2, lattice dimensions at -50 degrees C: a = 841.4(1), b = 924.2(1), c = 1550.0(1) pm, alpha = 90.046(7)degrees, beta = 95.671(9)degrees, gamma = 106.066(6)degrees, R-1 = 0.0329. In the molecular structure of 1 the scandium atom has a distorted trigonal-bipyramidal coordination with the THF molecules in apical positions. At 400 degrees C 1 is converted into scandium nitride, ScN, by stepwise leaving of THF and ClSiMe3.
