1′,3′,3′-Trimethyl-6-nitro-8-pyridiniomethylspiro[2H-[1]benzopyran-2,2′-indoline] chloride (1) was synthesized. Single crystals (crystal hydrates) of the open merocyanine form of compound1were obtained under the dark conditions, and their crystal structure was studied. On irradiation with visible light compound1crystallizes from propan-2-ol in the polycrystalline closed form. The spectral and photochemical properties of compound1in the polycrystalline state and the kinetic characteristics on thermal transformation of the closed form to the open form were studied.
