Abstract
- The asymmetric unit of the title mol-ecular salt [systematic name: 1,4,8,11-tetraazacyclotetradecane-1,8-diium bis(3-carboxy-prop-2-enoate)], C10H26N4 (2+)·2C4H3O4 (-), contains two half-cations (both completed by crystallographic inversion symmetry) and two maleate anions. The cyclam macrocycles adopt trans-III conformations, supported by two intra-molecular N-H⋯O hydrogen bonds. The O-bonded H atom of each maleate ion is disordered over two positions with an occupancy ratio of 0.61 (5):0.39 (5): each one generates an intra-molecular O-H⋯O hydrogen bond. In the crystal, the cations are linked to the anions by N-H⋯O hydrogen bonds, generating [001] chains.
