Phosphane Iminato Complexes of Arsenic. Crystal Structures of [AsCl(NPMe3)]2Cl2, [AsCl(NPMe3)2SbCl4]SbCl6, and [AsCl(NPMe3)2SnCl4] · CH3CN[AsCl(NPMe3)]2Cl2 (1) was prepared by the reaction of arsenic trichloride with the silylated phosphane imine Me3-SiNPMe3 in acetonitrile solution. According to the crystal structure determination, 1 has an ionic structure with [AsCl(NPMe3)]22+ ions, in which the As atoms are linked by the μ2-N atoms of the NPMe3- groups. Compound 1 reacts with antimony pentachloride to give [AsCl(NP-Me3)2SbCl4]+SbCl6- (2), with tin tetrachloride to form [AsCl(NPMe3)2SnCl4] (3), which is isoelectronic to the cation of 2. In 2 and 3 AsCl(NPMe3)2 acts as a chelating agent forming and , respectively, four-membered ring structures.
