摘要：

In the layered (NH3-R-NH3)(NH3-R-NH2)PbI5 (R=5,5'-bis(etliylsulfanyl)-2,2'-bithiophene) organic-inorganic hybrid compound, a PbI53- 1D network of corner sharing octahedra defines ordered deficient perovskite layers separated by the organic sheets. The NH3+... NH2 interactions together with NH3+...I contacts, which take place at the inorganic-organic interface, favor rather strong (SS)-S-... intermolecular interactions between bithiophene units, compared to those found in purely organic compounds or in (NH3-R-NH3)PbI4. Crystal data: (C24H35S8N4)PbI5, Mr = 1477.73, monoclinic, P2(1/c), a = 17.553(2) Angstrom, b = 8.710(1) Angstrom, c = 27.122(5) Angstrom, beta = 97.57(2)degrees, V = 411 0(1) Angstrom, Z = 4. R = 0.053, R-w = 0. 119. (C) 2003 Elsevier Inc. All rights reserved.
