Abstract

[W(O-t-Bu)₄(THF)] is formed from [WCl₄(SEt₂)₂] and LiO-t-Bu in boiling tetrahydrofuran and characterized by a crystal structure analysis. The compound crystallizes in the tetragonal space group I4 with Z = 2 and the lattice dimensions a = 6 = 1158.8(2) and c = 940.7(2) pm at 80°C. [W(O-t-Bu)₄(THF)] shows the molecular structure of a tetragonal pyramid with the oxygen atom of the THF molecule in the apical position. Surprisingly, the tungsten atom is deflected by 34 pm from the plane of the four oxygen atoms of the O-t-butyl groups against the direction of the W-O(THF) bond. The bonding modes are discussed on the basis of MO considerations.
