摘要
The crystal structure of solid dichlorodifluoromethane has been solved from powder neutron diffraction data. A single solid phase exists between the melting point and 1.5 K. The structure is orthorhombic, Fdd2, Z = 8, with a = 10.1676(3) angstrom, b = 14.9638(4) angstrom, and c = 5.1004(2) angstrom at 1.5 K. The molecules form columns with their dipole moments aligned ferroelectrically along the c direction.
