Abstract:
The donor-free potassium silanide K[SiPh₃] was prepared by the reaction of hexaphenyldisilane, Ph₃Si–SiPh₃, with potassium metal in benzene at room temperature. The solid-state structure, determined by powder X-ray diffraction consists of {K[SiPh₃]}₂ units, which interact with adjacent dimers to form an infinite chain along the crystallographic c axis (orthorhombic, space group Cmc2₁, Z=4). The structure features short contacts between the π system of the phenyl rings and the potassium atoms of neighbouring K[SiPh₃] units.
