Twisted fibers with a helical structure are formed by self‐assembly of chiral polyoxomolybdates (POMs) [(R*PO 3 ) 2 Mo 5 O 15 ] 2− (R=CH 3 CH(NH 3 ), CH 3 CH(CH 3 )CH(NH 3 )) through H‐bonding. High‐resolution TEM images of single fibers show an ordered substructure with parallel rows about 2 nm in width, in agreement with the packing of the H‐bonded POM subunits in the X‐ray structure (see inset).
