Halogenated closo-Dodecaborate Anions Stabilize Weakly Bound [(Me3NH)3X]2+ (X = Cl, Br) Dications in the Solid State

Cocrystallization of [Me3NH]2[B12Y12] (Y = Cl, Br, I) with 1 equiv. of [Me3NH]X (X = Cl, Br) from acetonitrile/diethyl ether solution produced large colorless single crystals of [(Me3NH)3X][B12Y12]. Four different compounds of this type were prepared and structurally characterized. The compounds consist of weakly coordinating perhalogenated closo-dodecaborate [B12Y12]2– dianions and unprecedented weakly bound discrete [(Me3NH)3X]2+ dications. The [(Me3NH)3X]2+ dications are built up from a central halide anion and three [Me3NH]+ cations bound by N–H···X hydrogen bonds. The cations have a pyramidal structure, as determined by X-ray diffraction, which is in contrast to quantum-chemical calculations, which predict a trigonal-planar structure. While the [(Me3NH)3Cl]2+ and [(Me3NH)3Br]2+ cations were easily prepared, attempts to synthesize the corresponding [(Me3NH)3F]2+ and [(Me3NH)3I]2+ cations failed. Three further crystal structures containing the angulated [(Me3NH)2X]+ cation stabilized by [B12Cl12]2–, [B12Br12]2–, or [Me3NB12Cl11]– are reported as well.

SUBSTITUTION OF THE ANION IN AMMONIUM AND PHOSPHONIUM CHLORIDES BY THE ACTION OF ELECTROPHILIC AGENTS

N,N-Dialkylmethaniminium iodides were obtained by the reactions of N,N-dialkylmethaniminium chlorides with methyl iodide.The reactions of ammonium and phosphonium chlorides with triethyloxonium tetrafluoroborate, dimethyl sulfate, methyl tosylate, and methyl iodide take place with substitution of the chloride ion by the BF4-, CH3SO3O-, p-CH3C6H4SO3- or I- ions.Substitution of the chloride ion of phosphonium salts by the iodide ion can be realized by the action of trimethyliodosilane.
