We have carried out an experiment to search for a neutron-rich hypernucleus, _Λ⁶H, by the ⁶Li(π^-,K⁺) reaction at p_π-=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 _Λ⁶H hypernucleus neither below nor above the _Λ⁴H+2n particle decay threshold. An upper limit of the production cross section for the bound _Λ⁶H hypernucleus was estimated to be 1.2nb/sr at 90% confidence level.
