Popis:	Single crystal neutron scattering measurements have been performed on the spin-ladder compound Sr 14 Cu 24 O 41 at 7 K. The incommensurate composite structure has been determined using the superspace group formalism. The low-temperature structure does not show a significant shift of the CuO 2 chains along the c direction. In addition to the main and satellite nuclear reflections compatible with the incommensurate composite structure, new weak super-structure peaks at Q=(h k L c ) , with L c = n ±0.20 (±0.01) have been observed. Their origin is probably due to the charge ordering associated to a three-dimensional configuration of the spin dimers in the CuO 2 chain.
