We performed both ^{119}Sn Möossbauer experiments and electronic structure calculations using the Korringa-Kohn-Rostoker method on the hexagonal RMn_{6}Sn_{6} (R = Mg, Zr, and Hf) compounds. According to previous neutron diffraction results two types of commensurate magnetic order are investigated: ferromagnetic for R = Mg and antiferromagnetic for R = Zr and Hf. From ^{119}Sn Möossbauer measurements, high transferred hyperfine fields on the tin nuclei are observed. The H_{hf} values are well supported by the Korringa-Kohn- Rostoker results. Moreover, the calculated μ_{Mn} are in good agreement with the neutron diffraction data. When observing the density of states, ZrMn_{6}Sn_{6} is found near semimetallic limit.
