摘要：
The crystal structure of an inclusion compound formed by triphenylmethanol with di-methylformamide was determined (space group P1 with a = 898.8(3) pm, b = 1022.3 pm, c = 1177.3pm, α =104.57(1)°, β = 110.32(1)°, γ = 96.76(1)°, Z = 2 at T = 300 K). The structure of compounds formed with acetone and dimethylsulfoxide were rerefined. A new assignment for the acetone compound in space group P21/n allowed a better ordered description of the molecule. The structure of the dimethylsulfoxide compound at 100 K did not indicate a phase transition and reproduced basically the room temperature structure.
