Abstract
The asymmetric unit of the hydrated title salt, (C10H28N4)[Cr2O7]2·H2O [C10H28N4 = H4(cyclam) = 1,4,8,11-tetraazoniacyclotetradecane], contains two half-cations (both completed by crystallographic inversion symmetry), two dichromate anions and one water molecule. The two [CrO7]2− anions exhibit a nearly staggered conformation, with bridging angles of 133.37 (11) and 136.28 (12)°. The distortions of the dichromate anions are due to their participation in hydrogen-bonding interactions with the water molecule and the cations. Intermolecular hydrogen bonds involving the cyclam N—H groups and water O—H groups as donor groups, and the O atoms of the dichromate anions as acceptor groups give rise to a three-dimensional network.
