A Three-Dimensional Porous Metal−Organic Framework with a Body-Centered Cubic Topology Constructed from 48-Membered Tetraicosanuclear Metallamacrocycle Based on in Situ Ligand Synthesis [PDF]

open access: yes, 2016
A three-dimensional metal−organic framework [Cd3(μ4-mtta)3(N3)3]·2.5H2O with [Cd24(N3)24] tetraicosanuclear metallamacrocycle as secondary building units (SBUs) and helical character is formed by self-assembly and in situ ligand synthesis.

Organoplatinum‐Bridged Cyclotribenzylene Dimers

open access: yesEuropean Journal of Inorganic Chemistry, Volume 26, Issue 25, September 1, 2023., 2023
Asymmetric cyclotribenzylenes (CTBs) incorporating an alkynyl and two nitrile functions were reacted with cis‐[PtL2Cl2] (L=PEt3 or L2=1,3‐bis(diphenylphosphino)propane) to afford Pt‐bridged CTB dimers. When CuI was used as synthetic auxiliary, (Pt, Cu) binuclear complexes in which a CuCl/CuI moiety was π‐coordinated to the platinum‐bound bis‐alkynyl ...

Fifty Years of Inorganic Biomimetic Chemistry: From the Complexation of Single Metal Cations to Polynuclear Metal Complexes by Multidentate Thiolate Ligands

open access: yesEuropean Journal of Inorganic Chemistry, Volume 26, Issue 10, April 3, 2023., 2023
This review shows, with selected examples, how the evolution of the coordination chemistry of transition metal cations with thiolate‐based ligands paralleled, at least in part, the concomitant development of bioinorganic chemistry during the last 50 years, with emphasis on the strategies directed at the controlled and reproducible synthesis of ...

A Chiral Pentadecanuclear Metallamacrocycle with a Sextuple Twisted Möbius Topology [PDF]

open access: yes, 2016
A C3 symmetric pentadecanuclear metallamacrocycle was obtained by the self-assembly of a pentadentate bridging ligand, N-phenylpropiolyl salicylhydrazide (H3L), and a manganese ion.

Manganese Metallamacrocycles with Various Coordination Solvents

open access: yesBulletin of the Korean Chemical Society, 2002
The hexanuclear metallamacrocycles were observed repeatedly in various conditions including the presence of several different tricationic metal ions in the macrocyclic ring system and of the linear alkyl chains at the acyl site of N-acylsalicylhydrazide ligand, which contrasts to the formation of the decanuclear metallamacrocycle with bulkier side ...

Structural Diversity of Alkaline Earth Centered Gold(I) Metallacoronates

open access: yesEuropean Journal of Inorganic Chemistry, Volume 2020, Issue 46, Page 4341-4349, December 13, 2020., 2020
Neutral gold(I) metallacoronates encapsulating alkaline earth metal ions are obtained by one‐pot reactions from catechol‐ or pyridine‐centered aroylbis(N,N‐diethylthioureas), alkaline earth salts and [AuCl(tetrahydrothiophene)]. Nuclearity and structures of the products depend on the organic framework of the thiourea ligands and the size of the ...

A M2L2 Redox-Active Metalla-Macrocycle Based on Electron-Rich 9-(1,3-Dithiol-2-ylidene)Fluorene

open access: yesInorganics, 2018
A redox-active M2L2 metalla-macrocycle is depicted, of which construction has been achieved through coordination driven self-assembly from an electron-rich 9-(1,3-dithiol-2-ylidene)fluorene bis-pyridyl ligand and a cis-blocked square planar palladium ...

Structural Versatility and Supramolecular Isomerism in Redox‐Active Tetra‐ and Hexaruthenium Macrocycles

open access: yesEuropean Journal of Inorganic Chemistry, Volume 2020, Issue 29, Page 2816-2829, August 9, 2020., 2020
Shaping Metallamacrocycles: Subtle variations of the preferred Ru···heteroatom···Ru angles of 2,5‐divinylfuran or ‐thiophene diruthenium complexes and of the O···heteroatom···O angles of 2,5‐thiophene‐, ‐furan‐ or pyrroledicarboxylic acid determine the preferred conformations and nuclearities of metallamacrocycles formed from these building blocks but ...

Observation of Near‐Infrared Photothermal and Photoacoustic Effects in a Metallosupramolecular Trefoil Knot

open access: yesAngewandte Chemie, Volume 137, Issue 48, November 24, 2025.
A metallosupramolecular trifold knot has been prepared from three bisimidazole ligands and three dinuclear half‐sandwich metal complexes. The topology of the trifold knot enforces strong π⋅⋅⋅π interactions between the building blocks, which results in near‐infrared (NIR) light absorption.

Self-assembly of Metallamacrocycles Employing a New Benzil-based Organometallic Bisplatinum(II) Acceptor

open access: yesCHIMIA, 2015
A benzil-based semi-rigid dinuclear-organometallic acceptor 4,4'-bis[trans-Pt(PEt3)2(NO3)(ethynyl)]benzil (bisPt-NO3) containing a Pt-ethynyl functionality was synthesized in good yield and characterized by multinuclear NMR (1H, 31P, and 13C ...
