Results of i.r. absorption and Raman scattering data and X-ray crystallographic data for lasalocid crystallized from methanol have enabled identification of two distinct structures for the 1: 1 lasalocid-methanolate complex. Both have space group P212121 but possess a different molecular geometry. The ketone carbonyl stretching frequency in the 1 700-1 730 cm-1 region is a sensitive indicator of crystalline modification.
