Synthesis and Crystal Structure of a New 2,6-dimethyl piperazine-1,4-diium Perchlorate Monohydrate: [C6H16N2](ClO4)(2) center dot H2O
Abstract
A proton transfer compound 2,6-dimethyl piperazine-1,4-diium perchlorate monohydrate was synthesized by slow evaporation at room temperature using 2,6-dimethyl piperazine as template. The asymmetric unit contains one organic dication, two crystal graphically independent perchlorate anions and one water molecule. Each organic entities is engaged in a large number of bifurcated and non-bifurcated N-H center dot center dot center dot O (O) and C-H center dot center dot center dot O hydrogen bonds with different species and enhanced the three dimensional supramolecular network. In addition, the diprotonated piperazine ring adopts a chair conformation with the methyl groups occupying equatorial positions.
