Guest Inclusion by N,N′,N″-Trihydroxyisocyanuric Acid: X-Ray Structure of the N,N-Dimethylformamide Complex

Abstract

The inclusion ability of N,N′,N″-trihydroxyisocyanuric acid 1 as a host is reported together with the X-ray crystal structure of a representative inclusion compound with formula 1·3(N,N-dimethylformamide). The latter crystallizes in the triclinic 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)°, γ = 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.
