• # Abstract

The reaction of benzyl chloride with tetramethylethylenediamine (tmen) results in the formation of the quaternary diammonium dichloride trihydrate (dbtmen)Cl2.3H2O 1 (dbtmen is N,N'-dibenzyl-N,N,N',N'-tetramethylethylenediammonium) in good yields. 1 crystallises in the monoclinic $P2_1/c$ space group and its structure consists of N,N'-dibenzyl-N,N,N',N'-tetramethylethylenediammonium dication, two chloride anions and three crystal water molecules all of which are located in general positions. The organic dication is H-bonded to the chloride anions and the crystal waters with the help of intra- and intermolecular C-H$\cdots$Cl and C-H$\cdots$O interactions, while the chloride anions are linked to the crystal waters via O-H$\cdots$Cl interactions. One of the crystal waters is linked through an intermolecular O-H$\cdots$O bond with another water resulting in the formation of a water dimer. The O-H$\cdots$Cl and O-H$\cdots$O interactions between the chloride anions and water molecules lead to the formation of a five-membered {O3Cl2} cyclic dichloride containing a water dimer. The five-membered rings are linked into a chain with the aid of a O-H$\cdots$Cl interaction. The organic cations are organised in zigzag fashion on either side of the chain and are further linked to the anionic water chain via weak C-H$\cdot$O and C-H$\cdots$Cl interactions, leading to the supramolecular organisation of the rings into a spiral-like of chain.
