VINΦ_{2}(TCNQ)_{2} is a salt with two different, non-parallel TCNQ stacks. The polarized reflectance spectra from single crystals in the IR region 660-5200 cm^{-1}, the powder absorption spectra 400-45000 cm^{-1} and FT-NIR Raman spectra of VINΦ_{2}(TCNQ)_{2} are measured at room temperature. More­over, the temperature dependence of powder absorption spectra in the fre­quency range 400-7900 cm^{-1} are studied. The nature of electronic bands, the anisotropy of optical conductivity, the temperature dependence of some vibrational bands and the charge distribution on different TCNQ stacks are discussed.
