    The lattice dynamics of NiI2 was studied at 4.2-300 K. The anisotropy of the oscillatory parameters is due to long-range Coulomb interactions. The polarizabilities were calcd as 5.6 × 10-24 for I- and 2.1 × 10-24 cm3 for Ni2+. The Szigeti effective charge is 0.30, indicating a large degree of covalency. [on SciFinder(R)]
