Guest Inclusion by N,N\u27,N"-Trihydroxyisocyanuric Acid: X-Ray Structure of the N,N-Dimethylformamide Complex

The inclusion ability of N,N′,N″-trihydroxyisocyanuric acid 1 as a host is reported together with the X-ray crystalstructure of a representative inclusion compound with formula 1·3(N,N-dimethylformamide). The latter crystallizes in thetriclinic space group P1 with unit-cell parameters a = 8.7938(1)Å, b = 10.5744(2)Å, c = 10.8076(2)Å, α = 91.731(1)°, β =109.910(1)°, ｒ= 95.785(1)° and Z = 2. Each solvent molecule is hydrogen bonded via its carbonyl oxygen atom to one of the hydroxyl groups of 1. Crystal packing was used to rationalise the observed thermal desolvation behavior of the inclusion compound
