Ñhemiluminescence (CL) upon the reaction of crystalline LnI2 (Ln = Dy, Nd) with water was found. The CL emitters are the Ln3+* electronexcited ions (Dy3+*, λmax = 470, 570 nm; Nd3+*, λ = 700—1200 nm) generated by the electron transfer from the LnII ions to the H2O molecules. The identified reaction products are H2, dissolved LnI3, and insoluble LnI(OH)2 (49—51% and 48—50% yield for DyI2 and NdI2, respectively). The treatment of NdI2 with an H2O solution in THF gives the NdI2OH(thf)2•3H2O complex and hydrogen.
