Losing an I : The metastable metallic compound Bi 28 Ni 25 is the product of the mild reduction of the solid precursor Bi 28 Ni 25 I 5 . In a pseudomorphosis the iodine is completely extracted while the macroscopic crystals are preserved. The unique structure is composed of decagonal nanorods, which consist of an outer Bi tube, an inner Ni tube, and additional Bi atoms along the central axis (see structure).
