The detection of molecular emission at -140 to -30 km/s localized within a few arcmin of Sgr A West in the 1-0 line of HNC is reported. The molecular gas is likely associated with the galactic center. This indicates that complex molecules do exist within the central 10 pc of the Galaxy. Spatial distribution of the molecular gas is asymmetric with respect to the galactic center, and it appears likely that the gas is not purely rotating but is moving radially into or out of the galactic center. The duration of the phenomenon is estimated to be less than about 50,000-100,000 years.
