A series of new hybrid iodometallates [H4Spiro-4-py]n[Cu7I10]n(I3−)n·0.5(I2)n·nH2O (1), [Cu2I2(Spiro-3-py)]n·0.75n(DMF)·0.25nH2O (2), [H2Spiro-4-py][H3Spiro-4-py][Ag10I20]0.5·H2O (3) and [H2Spiro-4-py]n[H3Spiro-4-py]n[Ag8I13]n·2.5H2O (4) were hydrothermal synthesized. 1 contains 1-D chain [Cu7I10]n based on new [Cu7I12] cluster, free I3− anions and I2 molecules, which are interconnected by weak I⋯I interactions to generate a novel polyiodide {[Cu7I10](I3−)·(I2)}n framework. 2 features a neutral sql layer [Cu2I2(Spiro-3-py)]n constructed by the interconnection of the {Cu2I2} dimers and Spiro-3-py ligands. The anionic [Ag10I20]10− framework of 3 can be described as an aggregation of two tetrameric [Ag4I8] clusters and one dimeric [Ag2I6] unit via sharing corner. The 1-D anionic chain [Ag8I135−]n of 4 is built up from the alternate connection of tetrameric [Ag4I8] units and rare larger [Ag12I20] clusters, which offers the only example of 1-D iodoargentates based on two types of iodoargentate clusters. The optical and photoelectronic properties of all compounds were also investigated.
