Crystal structure of propane-1,3-diaminium squarate dihydrate.

ABSTRACT: Propane-1,3-diaminium squarate dihydrate, C₃H₁₂N₂ ²⁺·C₄O₄ ^2-·2H₂O, results from the proton-transfer reaction of propane-1,3-di-amine with squaric acid and subsequent crystallization from aqueous medium. The title compound crystallizes in the tetra-gonal crystal system (space group P4bm) with Z = 2. The squarate dianion belongs to the point group D _4h and contains a crystallographic fourfold axis. The propane-1,3-diaminium dication exhibits a C _2v -symmetric all-anti conformation and resides on a special position with mm2 site symmetry. The orientation of the propane-1,3-diaminium ions makes the crystal structure polar i
