摘要：

Polarized reflectivity spectra of a new organic conductor BEDO5[CsHg(SCN)(4)](2) were measured in the spectral range of 700-6500cm(-1) at 300-10 K. An anisotropy of temperature behavior of optical conductivity in the conducting plane was observed, it shows metallic character for the direction perpendicular to BEDO stacks and non-metallic behavior for the direction parallel to BEDO stacks, where a growth of a broad band at near 4000 cm(-1) testifies for the appearance of an energy gap. Fitting by the Drude-Lorentz model points on an existence of a low-frequency energy gap. The gaps may appear due to dimerisation of BEDO molecules in the stacks at low temperatures.
