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. Workplace Institute of Physics Contact Kristina Potocká, potocka@fzu.cz, Tel.: 220 318 579 Year of Publishing 2017
