First exfoliated Ru–Ru–Au organometallic polymer with layered structure

A novel Ru–Ru–Au 3D heterometallic polymer self-assembles in single layers with large scale hexagonal conformation, as well as forming 3D stacks of polymer sandwiches.

Water driven formation of channels: unusual solid-state structural transformation of a heterometallic polymer

We describe the synthesis of trans-{[(PTA)2CpRu-μ-CN-RuCp(PTA)2-μ-CoCl3]}n·(DMSO)n, and its crystal-to-crystal transformation to its cis isomer, with channels where water is nanoconfined, upon addition of water to the crystallization medium.

Iron molybdenum nitrilotriacetate and iminodiacetate – spectroscopy, structural characterization and CO2 adsorption

The tetranuclear iron molybdate Na6[(MoO2)2O2Fe2(nta)4]·16H2O (1) and its isomorphous complexes form 2D water layer structures in a modular manner, and a decanuclear heterometallic polymer, [(MoO4)2FeII4FeIII4(ida)8]n (2), contains an interesting cubic 3D microporous structure with a 3.3 Å diameter hole and can adsorb a small amount of CO2.

Unequal coordination environment in complexes of the type [Au2Ag2(R)4(L)2]n. An immiscible solvent mixture as a key point in the control of ligand replacement

A new photoluminescent heterometallic polymer [Au6Ag6(C6Cl2F3)12(μ2-pym)2(NCMe)6]n (2) with three different coordination environments has been synthesised.

A tubular one-dimensional polymer constructed from alternating clusters of europium(III)–water and copper(I) chloride bridged by 4-(pyridin-4-yl)benzoate

A new 3d–4fheterometallic polymer, poly[[aqua-μ3-chlorido-[μ3-4-(pyridin-4-yl)benzoato]tris[μ2-4-(pyridin-4-yl)benzoato]dicopper(I)erbium(III)] dihydrate], {[Cu2Er(C12H8NO2)4Cl(H2O)]·2H2O}n, was synthesized by the hydrothermal reaction of Er2O3, CuCl2·2H2O and 4-(pyridin-4-yl)benzoic acid in the presence of HClO4. The asymmetric unit contains one Er3+cation, two Cu+cations, one Cl−anion, four deprotonated 4-(pyridin-4-yl)benzoate ligands, one coordinated aqua ligand and two solvent water molecules. This tubular one-dimensional polymer is constructed from alternating clusters of europium(III)–water and copper(I) chloride bridged by 4-(pyridin-4-yl)benzoate ligands. Extensive hydrogen-bonding interactions involving both the coordinated and the solvent water molecules provide further stabilization to the structure.
