Notes:
Tet-b (racemic 5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane, C16H36N4) and trimesic acid (1,3,5-benzenetricarboxylic acid, C9H6O6) form a salt partially solvated by both water and methanol, i.e. 5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane–1,3,5-benzenetricarboxylic acid–methanol–water (1/1/0.78/1.12), C16H38N42+·C9H4O62−·0.78CH4O·1.12H2O. The anions are linked by O—H...O hydrogen bonds [O...O 2.442 (4) and 2.458 (4) Å; O—H...O 170 and 171°] into zigzag chains; orientationally disordered cations are linked to the anion chains by means of N—H...O hydrogen bonds [major orientation: N...O 2.695 (3)–3.071 (4) Å, N—H...O 148–179°; minor orientation: N...O 2.75 (2)–3.34 (2) Å, N—H...O 147–170°] and link the chains into sheets. The solvent molecules are all disordered, but appear to play no significant structural role apart from space filling.
