摘要：

Layered compounds have been synthesized and structurally characterized for the n = 5 and 6 members of the perovskite-related family La4Srn-4TinO3n+2 by combining X-ray diffraction and transmission electron microscopy. Their structure can be regarded as comprising [(La,Sr)(5)Ti5O17] and [(La,Sr)(6)Ti6O20] perovskite blocks joined by crystallographic shears along the a-axis, with consecutive blocks shifted by 1/2 [100](p). The n = 5 member is similar to the previously reported n = 5 member of other A(n)B(n)O(3n+2) related series. The it = 6 member, which has only been briefly reported in other systems previously, is also a well-behaved member of this A(n)B(n)O(3n+2) series. (C) 2004 Elsevier Inc. All rights reserved.
