title: Pb5In3Bi5S17 [Pb(4.94(3))In(3.05(3))Bi(4.99(3))S17] and its structural relationship with Pb4In3Bi7S18.
abstract: The title phase (pentalead triindium pentabismuth heptadecasulfide) has been synthesized and structurally characterized. Its structure contains mixed Bi/In, In/Bi and Pb/In positions; all atoms lie on crystallographic mirror planes. The structural relationship between Pb(5)In(3)Bi(5)S(17) and a phase known by the formula Pb(4)In(3)Bi(7)S(18) is discussed. A comparatively large and complex structural `seed' is defined which is common to both phases. The structural changes within this seed when moving from one phase to the other are described by graphical means.
