摘要：

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 Cmc2(1), Z=4). The structure features short contacts between the pi system of the phenyl rings and the potassium atoms of neighbouring K[SiPh3] units.
