Abstract: In the title compound {systematic name: 9-[bis(trimethylsilylethynyl)methylene]fluorene}, C₂₄H₂₆Si₂, the molecules are planar (except for the methyl groups) and pack in layers parallel to the bc plane at x $\simeq$ $1\over4$ and $3\over 4$ . The mean distance between neighbouring layers, which are related by inversion, is 3.50 Å.
