Fourier transform IR absorption spectra of single crystals of the (ET)_{2}C_{60} complex grown from the CS_{2} solution as well as its components: C_{60} and ET, also grown from CS_{2} solution, are presented and discussed. It is shown that the rotation of C_{60} is strongly hindered and ET molecules are bent in the crystal structure of the complex. The arguments for the domination of the van der Waals interactions are given.
