Zeolite-like Copper Iodide Framework with New 6⁶ Topology

Abstract

We have described an unprecedented three-dimensional zeolite-like copper iodide constructed from Cu4I4(DABCO)4 (DABCO = 1,4-diazabicyclo[2.2.2]octane) supertetrahedron units. This compound forms a four-connected network with new 6(6) topology. Its structure reveals one-dimensional channels along the [001] direction, and the framework displays interesting self-penetration. The title compound shows photoluminescence at room temperature in the solid state.

A self-penetrated chiral cobalt camphorate coordination polymer with antiferromagnetically coupled paddlewheel clusters

“…In comparison to crystalline coordination polymer phases with interpenetration of identical networks [11], phases exhibiting selfpenetration are less common [12][13][14][15][16][17][18][19][20][21]. In these materials, connecting rods of the network penetrate through the shortest circuits of the same network.…”

“…Some of the appeal for basic research in this area is certainly aesthetic, as their three-dimensional networks often display beautiful network topologies, sometimes related to known mineral structure types (e.g., α-Po, PtS, SrAl 2 ) [8]. Chiral coordination polymers can exhibit facility for separation of enantiomers [9] or heterogeneous catalysis for the production of optically active organic compounds [10], indicating a fruitful area for more aggressive crystal design efforts.In comparison to crystalline coordination polymer phases with interpenetration of identical networks [11], phases exhibiting selfpenetration are less common [12][13][14][15][16][17][18][19][20][21].

Reversible Interconversion between Luminescent Isomeric Metal–Organic Frameworks of [Cu4I4(DABCO)2] (DABCO=1,4‐Diazabicyclo[2.2.2]octane)

“…[2][3][4] Although copper(I) iodide and bidentate ligands have been employed in the preparation of metal-organic framework (MOF) compounds, those containing cubane-like clusters are less common. [5][6][7][8][9][10][11][12][13][14][15] Moreover, iodide clusters of Cu I show unique luminescence properties that have been the subject of great interest over the last 40 years, [16][17][18][19][20] and have been associated with attractive Cu···Cu (cuprophilic) interactions. [21,22] We have long been interested in the preparation of metal-organic as well as hybrid organic-inorganic framework compounds [23][24][25] within the scope of our crystal engineering endeavours.…”

Synthesis, crystal, luminescent properties and electronic structures of two copper(I) halide polymers based on Cu4I4 cubane tetramers

“…Moreover, copper(I) halides exhibit fascinating frameworks and intriguing topologies with abundant structural motifs, such as rhomboid Cu 2 X 2 dimers [7], cubane or stepped-cubane Cu 4 X 4 tetramers [8-10], zigzag [CuX] n chains, double-stranded [Cu 2 X 2 ] n ladders [11], and banded ribbons or hexagon prism [Cu 6 X 6 ] n grid chains [12,13]. However, among these types of clusters, in particular, the Cu 4 X 4 tetramers are widely designed as building blocks in the formation of the materials due to the excellent inorganic functional modules with tetrahedral connectivity as well as its rich luminescent properties with auxiliary nitrogen-containing organic ligands [14][15][16][17]. The organic component plays an equally important role in these hybrid compounds, in shaping their conformational, structural, and properties [18].…”
