Cubane Complexes with Two (or More) Group 14−Group 16 Double Bonds: Synthesis and X‐ray Structures of Sn₄Se₂(N<i>t</i>Bu)₄ and Ge₄Se₃(N<i>t</i>Bu)₄

Abstract

Abstract Monomeric complexes with two or three terminal M=Se bonds, Sn 4 Se 2 (N t Bu) 4 or Ge 4 Se 3 (N t Bu) 4 , respectively, are produced by oxidation of (MN t Bu) 4 (M = Sn, Ge) with selenium in hot toluene. (© Wiley‐VCH Verlag GmbH &amp; Co. KGaA, 69451 Weinheim, Germany, 2003)
