Tris(dimethylphenylsilyl)antimony ( 1 ) was prepared in moderate yield from dimetallic “Na 3 Sb” (generated in situ) and chlorodimethylphenylsilane in tetrahydrofuran at reflux temperature. The product was identified by standard analytical and spectroscopic techniques, and the crystal structure was determined by single‐crystal X‐ray diffraction (triclinic, space group P 1, Z = 2). The SbSi 3 skeleton is pyramidal (average Si‐Sb‐Si angle 100.2°, average Sb‐Si bond length 2.558 Å), and the Me 2 PhSi groups are in a staggered conformation.
