title: 2-(2-Ammonio-ethyl)pyridinium hexa-chloridorhenate(IV).
abstract: In the title anti-ferromagnetic material, (C(7)H(12)N(2))[ReCl(6)], the Néel temperature is observed at 5 K. The salt is stabilized by an extensive network of N-H⋯Cl and C-H⋯Cl hydrogen bonds, where hydrogen-bonded anion chains and characteristic cation-anion motifs are present. Similar systems play an important role in crystal engineering as hydrogen bonds that can transmit magnetic inter-actions.
