A search has been made for the superheavy isotope of hydrogen, 6H, whose existence has been claimed in two heavy ion experiments. The pion double charge exchange reaction 6Li(π-, π+)X at T(π-)= 220MeV was used in a high-resolution search for 6H. No evidence for 6H was found anywhere in the missing mass range -10 to +30 MeV. In the missing mass region 0-5 MeV 95% confidence upper limits of 0-5 nb/sr for the production cross section were set.
