The incommensurate modulated crystal structure of Bi2.27Sr1.73CuO6+δ (2201) phase [the (3 + 1)-dimensional monoclinic A2/a( a0g ) group] has been refined with R = 0.041, wR = 0.052 from X-ray single-crystal data including up to third-order satellite reflections. The same structure has also been considered as incommensurate composite with a2 = 2.437, b2 = 5.387, c2 =24.614, 2 = 93.06, q2 = 0.4524a2*- 0.243c2* and the (3 + 1)-dimensional A2/m( 0 )0s group for the second component. Both approaches give quitesimilar results.
