A new sesquiterpenoid with an aromadendrane skeleton, halichonadin F (1), and the Cu(I) complex of haliconadin C (2) were isolated from a marine sponge Halichondria sp., and the structures and relative stereochemistries of 1 and the complex of 2 were elucidated on the basis of spectroscopic data and chemical methods.
