文摘
We report the preparation, crystallization, and solid-state characterization of the first member ofa new family of tris(1,9-disubstituted phenalenyl)silicon neutral radicals. In the solid state, the radical packsas weak partial 
-dimers with intermolecular carbon···carbon contacts that fall at the van der Waals atomicseparation. Magnetic susceptibility measurements indicate ~0.7 Curie spins per molecule from roomtemperature down to 50 K, below which antiferromagnetic coupling becomes apparent; the compound hasa room-temperature single-crystal conductivity of 
RT = 2.4 × 10-6 S cm-1.
