Role of Bis(triphenylphosphine)iminium Cation [PNP]+ on the Crystal Packing of [PNP]+[HSeO3]− Solvate Salt

摘要: Selenate(IV) and hydrogen selenate(IV) salts of bulky cations are very interesting compounds for synthetic kinetic studies. In this work, bis(triphenylphosphine)iminium ([PNP]+) chloride has been used, which aims to synthesize the corresponding salt by an exchange reaction in aqueous solution subsequent crystallization solvent evaporation. Unexpectedly, procedure afforded a solvate form [PNP]+[HSeO3]− (1). solid phase, structure that is determined Single Crystal XRD, anion tends maximize interactions with itself, although it leaves cationic moiety have only weak anions molecules. turn, latter builds network effective bonds. This behavior opposes general tendency selenite(IV) compounds, since these commonly found formed bonds surrounding chemical species. Moreover, as non-quantitative, exceeding traces starting reagent reacted bis(acetonitrile)dichloropalladium(II) hexachloropalladate (2). [PNP]+ causes absence strong supramolecular interactions, highlights peculiar cation crystal packing its phases.
