Abstract: Ahydrogen-bonded supramolecular compound, [H3cth] [Fe(CN)6]. 3H2O, was synthesized from meso-5, 7, 7, 12, 14, 14-hexamethyl-1, 4, 8, 11-tetraazacyclotetradecane (cth) and K3 [Fe (CN )6]. The compound crystallizes in triclinic space group P1, with a=0. 93097 (9) nm, b=1. 05160(11) nm, c=1. 63847(17) nm, a=101. 077(2)°,β=90. 860(2)°, γ=111. 671 (2)°, V=1. 4564(3) nm3, Z=2, R=0.0415. The structure consists of neutral two-dimensional sheets assembled via hydrogen bonds be- tween the partially protonated macrocyclic tetraamine and the hexacyanoferrate(Ⅲ) ion, while the hydrogen bonds involving water molecules interlink the sheets to form a unique three-dimensional supramolecular architecture.
