Reaction of RLi [R = CH(SiMe₃)₂] with BiCl₃ in a 2:1 ratio gives R₂BiCl (1). RBiPh₂ isformed by the action of RMgCl on Ph₂BiCl. Reaction of RBiPh₂ with HCl in CHCl₃ givesRBiCl₂ (2), which crystallizes from diethyl ether as the solvate 2·0.5Et₂O. The crystalstructures of 1 and 2·0.5Et₂O have been determined by X-ray diffraction. Crystals of 1 consistof pyramidal R₂BiCl molecules, whereas in crystals of 2·0.5Et₂O there are journals/orgnd7/18/i03/eqn/om9806444e10001.gif">{[RBi(Cl)Cl]₂·Et₂O}_x chains with chloro bridges. The diethyl ether molecules are weakly associatedto neighboring bismuth atoms in the chain.
