Abstract: The crystals of (BEDT-TTF)$_4$K[Fe(CN)$_5$NO]$_2$, representing a quasi-two-dimensional organic metal with conducting layers of bis(ethylenedithio)tetrathiofulvalene (BEDT-TTF) and nonconducting layers containing pho-tochromic nitroprusside anions [Fe(CN)$_5$NO]$^{2-}$, were studied by the method of electron spin resonance. Illuminated by light with a wavelength of 514.5  nm, the organic metal crystals feature the formation of localized paramagnetic centers in the conducting cation layers of BEDT-TTF. The phenomenon of electron localization in the BEDT-TTF layers is related to the light-induced formation of long-lived metastable states of nitroprusside anions.
