New Framework Iodoargentates: M(en)₃Ag₂I₄ (M = Zn, Ni) with Tridymite Topology

Abstract

Two novel framework compounds, Zn(en) 3Ag2I4 (1) and Ni(en) 3Ag2I4 (2), have been synthesized by a self-assembly reaction. Both of them contain an unexpected framework, Ag2I4(2-) with tridymite topology, and the discrete M(en)3(2+) cations are located in the channels. Their thermal properties and circular dichroism spectra were investigated.

Introducing p-block metals into iodoargentates: structures and properties of two new heterometallic hybrids

“…For silver halide systems, incorporation of organic components into silver/halide structures has been realized by using low-temperature procedures [7][8][9][10][11][12]. A recent advance in this system is obtaining materials by introducing a heterometal together with ligands into silver halide inorganic skeletons [13][14][15][16][17][18]. Two situations have been found: (1) the second metal coordinates with ligands (ML n ) to act as structure directing agent without direct binding with the inorganic frameworks and (2) the second metal dopes into the silver halide skeleton to give heterometallic frameworks.…”

Tripyridine‐Derivative‐Derived Semiconducting Iodo‐Argentate/Cuprate Hybrids with Excellent Visible‐Light‐Induced Photocatalytic Performance

“…The halide ions (Cl − , Br − , I − ) can serve as bridges from terminal to μ 2 ‐ and up to μ 8 ‐bridging. The combination of halide ions and different metal atoms, directed by various organic templates, has formed numerous captivating structures . Recently, Guo et al.…”

Alternating-current conductivity and dielectric relaxation of bulk iodoargentate

“…In these systems, the inorganic building-block of silver(I) halide occupy an important position for their versatile topology structures and enthralling properties such as good electrical mobility, band gap tenability, mechanical and thermal stability. So far, considerable progress is being made toward the goal of obtain specific architectures: for example, the chiral framework iodoargentates with tridymite topology [3], the Ag 10 quadruple helicate, and undecanuclear silver clusters containing an unusual m 9 -iodide [4].…”
