We have carried out an experiment to search for a neutron-rich hypernucleus, $$^6_Lambda$$H, by the $$^{6}$$Li($$pi$$$$^{-}$$,K$$^{+}$$) reaction at p$$_{pi-}$$ = 1.2 GeV/c. The obtained missing-mass spectrum with an estimated energy resolution of 3.2 MeV (FWHM) showed no peak structure corresponding to the $$^6_Lambda$$H hypernucleus neither below nor above the $$^4_Lambda$$H+2n particle decay threshold. An upper limit of the production cross section for the bound $$^6_Lambda$$H hypernucleus was estimated to be 1.2 nb/sr at 90% confidence level.
