Compounds of Germanium and Tin, 16. A Tetraaryldistannene with a Long Tin-Tin Multiple Bond and Differing Environments at the Tin Atoms

Although tetrakis(2‐tert‐butyl‐4,5,6‐trimethylphenyl)distannene (9), the first tetraaryl‐distannene to be reported on, is stable in the solid state, only the monomeric stannylene 8 can be detected in solution. An X‐ray crystal structure analysis of 9 reveals a long tin‐tin bond length of 291.0(1) pm and a trans‐bent Sn2C4 framework with different fold angles of 21.4° and 64.4°. M. Weidenbruch*, H.
