NGC 5850 is a large, nearby SB(r)b spiral that is an apparent member of the NGC 5846 group of galaxies (de Vaucouleurs 1975; Turner & Gott 1976). The mean corrected redshift of this group is ā1900 km sā1 (Haynes & Giovanelli 1991). We have obtained broadband imaging and VLA HI interferometry of this galaxy as part of a general study of its properties. The most noteworthy characteristic of the galaxy is a severe distortion of the outer regions. This distortion is most likely due to an interaction with another member of the group, possibly NGC 5846 or its companion NGC 5846A, which are only 10' to the northwest. In this paper we summarize some of the results of the optical and HI analysis, and highlight the effects of the interaction.
