2-Amino-4-methoxy-6-methylpyrimidine (AMMP) is a pyrimidine derivative. It acts as electron donor and forms charge transfer complexes with iodine (σ-electron acceptor). The FTIR and FT-Raman spectra of 2-amino-4-methoxy-6-methylpyrimidine have been recorded to evaluate the energy, structural and thermodynamical parameters. Molecules of AMMP exhibit space group of Pnma and are joined by two N-H…N hydrogen bonds.
