Abstract

Organic hybrid lanthanide(III) iodoargentates [Ln(DMSO)8]4Ag22I34·2H2O (Ln = La (1), Ce (2)), [Ln(DMSO)8]Ag7I10 (Ln = Eu (3), Tb (4), Dy (5)), and [Yb(DMSO)7]Ag5I8 (6) (DMSO = dimethyl sulphoxide) were synthesized by a diffusion method and structurally characterized. In 1 and 2, twenty AgI4 tetrahedra and two AgI3 triangles are connected via edge-sharing, forming the highly nuclear cluster [Ag22I34]12−. In 3–5, the 2D [Ag7I103−]n layer is constructed from Ag10I18 and Ag2I5 secondary building units via edge-sharing. The parallel packing of the [Ag7I103−]n layers generates channels with cross-sectional dimensions of 5.5 × 18.2 Å2, in which the [Ln(DMSO)8]3+ counterions are trapped. In 6, three AgI4 and two AgI3 units are joined via corner- or edge-sharing to form the asymmetric structural unit Ag5I8. The Ag5I8 units are interconnected into a 1D [Ag5I83−]n chain via corner-sharing. The formation of [Ag22I34]12−, [Ag7I103−]n and [Ag5I83−]n anions indicates the different structure-directing effects of the Ln(III) ions across the lanthanide series. Compounds 3 and 4 display intense red and green luminescence at room temperature excited by 393 and 369 nm light, respectively.
