The first anti-tricyclo[,4]hexasilane 1 was synthesized as pale yellow crystals. Irradiation (λ > 370 nm) of 1 gave its skeletal isomer, tricyclo[,5]hexasilane 2, in 80% yield. The photochemical [σ2s + σ2S] cycloreversion of 1 followed by the thermal [π2S + π2a] cycloaddition to 2 would explain the overall isomerization.
