Red‐orange crystals of cyclotrisilene 3 were obtained by the reaction of the dibromotrisilane 1 and the tribromodisilane 2 with sodium in toluene [Eq. (1)]. The X‐ray crystal structure of 3 shows that the three‐membered ring is almost an isosceles triangle and has a twisted Si−Si double bond with a length of 2.138(2) Å.
