Abstract: The reaction of (2-hydroxyethyl)diisopropylammonium chloride with CoCl₂·6H₂O has resulted in the unusual formation of a quaternary piperazinium salt with the formula (tippipz)[CoCl₄], where tippipz is tetraisopropylpiperazinium (C₁₆H₃₆N₂²⁺). The structure of this compound consists of sheets of organic ammonium dications and inorganic dianions formed by C-HCl hydrogen bonds.
