    Description / Table of Contents: Preparation and Crystal Structure of Rubidium Triiodoplumbate(II)RbPbJ3 crystallizes in the orthorhombic space group Pnam(D2h16) (lattice parameters see above); it is isomorphous with CsPbJ3. The crystal structure has been determined from 1452 independent reflexes by Patterson- and Fourier-syntheses and refined three dimensionally by least-squares-methods.6 I surround Pb nearly octahedrally. The octahedra are arranged in the form of double chains along the c-axis, which are held together by Rb. (Pb—I bond distances see above). The “inert 6s-pair” at Pb is stereochemically inactive.
    Notes: RbPbJ3 kristallisiert orthorhombisch in der Raumgruppe Pnam (D2h16) mit a = 10,274(1), b = 17,381(2), c = 4,773(1) Å und Z = 4; es ist isomorph mit CsPbJ3. Die Kristallstruktur wurde anhand von 1452 unabhängigen Reflexen mittels Patterson- und Fourier-Synthesen bestimmt und nach der Kleinste-Quadrate-Methode dreidimensional verfeinert.Pb ist nahezu oktaedrisch von 6 J umgeben. Die Oktaeder bilden längs der c-Achse Doppelketten, die von Rb zusammengehalten werden. Die Pb-J-Bindungsabstände betragen 3,037(2), 3,382(2), 3,224(1), 3,253(1) Å. Das „inerte 6s-Elektronenpaar“ des Pb tritt sterisch nicht in Erscheinung.
