Abstract

The NaNCS complex of the macrotetrolide antibiotic nonactin, which acts as an ionophore with biological and artificial membranes crystallizes in the space group C2/c, a = 15.55, b = 19.59, c = 15.31 Γ…, Ξ² = 90Β°. The X‐ray crystal structure investigation shows that Na^+^ is coordinated by four carbonyl oxygen atoms (Na^+^ … O, 2.42 Γ…) and four ether oxygen atoms (Na^+^ … O, 2.77 Γ…). The cubic coordination by eight equidistant oxygen atoms observed in the K^+^ complex (K^+^ … O, 2.81 Γ…) is thus deformed. This, however, requires only very small changes in the ligand conformation.
