Self-Assembly of a Series of Extended Architectures Based on Polyoxometalate Clusters and Silver Coordination Complexes Haiyan An Yangguang Li Enbo Wang Dongrong Xiao Chunyan Sun Lin Xu 10.1021/ic050636x.s003 https://acs.figshare.com/articles/dataset/Self_Assembly_of_a_Series_of_Extended_Architectures_Based_on_Polyoxometalate_Clusters_and_Silver_Coordination_Complexes/3271825 Three unusual compounds based on polyoxometalate building blocks, [(H<sub>2</sub>O)<sub>5</sub>Na<sub>2</sub>(C<sub>6</sub>NO<sub>2</sub>H<sub>4</sub>)(C<sub>6</sub>NO<sub>2</sub>H<sub>5</sub>)<sub>3</sub>Ag<sub>2</sub>][Ag<sub>2</sub>IMo<sub>6</sub>O<sub>24</sub>(H<sub>2</sub>O)<sub>4</sub>]·6.25H<sub>2</sub>O (<b>1</b>), [(H<sub>2</sub>O)<sub>4</sub>Na<sub>2</sub>(C<sub>6</sub>NO<sub>2</sub>H<sub>5</sub>)<sub>6</sub>Ag<sub>3</sub>][IMo<sub>6</sub>O<sub>24</sub>]·6H<sub>2</sub>O (<b>2</b>), and (C<sub>6</sub>NO<sub>2</sub>H<sub>6</sub>)<sub>2</sub>[(C<sub>6</sub>NO<sub>2</sub>H<sub>5</sub>)<sub>2</sub>Ag][Cr(OH)<sub>6</sub>Mo<sub>6</sub>O<sub>18</sub>]·4H<sub>2</sub>O (<b>3</b>), have been synthesized and characterized by elemental analysis; IR, XPS, and ESR spectroscopy; TG analysis; and single-crystal X-ray diffraction. Compound <b>1</b> is constructed from the cationic two-dimensional (2D) coordination polymer sheets which are constituted of [(H<sub>2</sub>O)<sub>5</sub>Na<sub>2</sub>(C<sub>6</sub>NO<sub>2</sub>H<sub>4</sub>)(C<sub>6</sub>NO<sub>2</sub>H<sub>5</sub>)<sub>3</sub>Ag<sub>2</sub>]<sup>3+</sup> and anionic [Ag<sub>2</sub>IMo<sub>6</sub>O<sub>24</sub>(H<sub>2</sub>O)<sub>4</sub>]<sup>3-</sup> chains as pillars, forming a three-dimensional (3D) supramolecular framework via weak Ag−O interactions. Compound <b>2</b> is composed of the well-defined [IMo<sub>6</sub>O<sub>24</sub>]<sup>5-</sup> building blocks, which are linked through trinuclear Ag-pyridine-3-carboxylic acid, [(C<sub>6</sub>NO<sub>2</sub>H<sub>5</sub>)<sub>6</sub>Ag<sub>3</sub>]<sup>3+</sup>, fragments into a one-dimensional (1D) hybrid chain; adjacent chains are further connected by sodium cations to yield a novel 2D network. Compound <b>3</b> has a 1D chainlike structure constructed from [Cr(OH)<sub>6</sub>Mo<sub>6</sub>O<sub>18</sub>]<sup>3-</sup> building blocks and Ag-pyridine-4-carboxylic acid coordination units.
