摘要：

Fullerite C-60 with intercalated CH2F2 (Freon-32) was prepared for the first time. The sample was studied by elemental analysis, X-ray powder diffraction, mass spectrometry, and IR spectroscopy. The composition of the sample was found to be (CH2F2)C-60. The sample had a face-centered cubic lattice with the lattice parameter (1.4284 nm) much larger than that of pure fullerite (1.416 nm). The gas released from the sample during heating in a vacuum to 450 degrees C largely consisted of initial Freon (mass spectrometry data); no Freon destruction products were observed at this temperature. The C-F stretching vibration frequency (1058 cm(-1)) was shifted in (CH2F2)C-60 by 30 cm(-1) toward lower wave numbers compared with the gas phase. The absorption bands at 1182 and 1428 cm(-1) (IR active modes (F-1u ) of high-symmetry (I (h)) C-60 molecules) did not change their positions in the intercalate.
