The crystal structure of thiourea:diethyl oxalate at 100k was solved using single crystal x-ray diffraction. The system crystallized in triclinic system, similar to that at room temeperature. No phase transition is observed at low temperature. The R-factor obtained was R[F2 > 2Σ(F2)] = 0.03. The crystal structure at low temperature induces closer packing of the molecules and general shrinkage of the unit cell and shortening of the hydrogen bonds to the by about 2%.
