Structural variation from heterometallic heptanuclear or heptanuclear to cubane clusters based on 2-hydroxy-3-ethoxy-benzaldehyde: effects of pH and temperature

Abstract

Five novel clusters were reported, with results showing that pH and reaction temperatures have a key role in the self-assembly process.

Tetranuclear MnII/ZnII and Novel Azido‐Bridged Chair‐Shaped Heptanuclear CdII Compounds: The Effect of Metal Ion and Coordination Mode of the Azide Group on the Structure of the Products

“…Although similar complexes with metals bridged by azide anions have been reported containing wheel‐shaped Co 7 (L = 2‐hydroxy‐[1,2‐di(pyridin‐2‐yl)]ethane‐1‐one and 2‐methoxy‐6‐[(methylimino)methyl]phenol) and heteronuclear Ni 4 Na 3 and Co 4 Na 3 clusters (L = 2‐hydroxy‐3‐ethoxy‐benzaldehyde), all having µ 3–1,1,1 ‐N 3 connecting ligands, but at our knowledge no example of Cd 7 member bridged by azido ligands have been reported to date. Few examples of heptanuclear Cd II compounds are available in the literature , .…”

Diverse Structures Based on a Heptanuclear Cobalt Cluster with 0D to 3D Metal–Organic Frameworks: Magnetism and Application in Batteries

“…As shown in Figure S2, the disc‐like heptanuclear clusters are well isolated from each other through H 6 L ligands, methoxy groups, and Cl − ions. The structure motif constructed by the closest‐packing of donor nitrogen/oxygen and cobalt ions is part of the expanding [M 7 ] family, which has been explored previously –…”

High Efficiency Electrochemiluminescence for Copper(II) and Cadmium(II) Pyrazolate Polymers

“…The design and selection of organic ligands and metal ions are critical factors for the construction of CPs, due to the coordination mode of organic ligands and functional groups in them are directly affect the configuration and applications of the CPs. However, it is a great challenge to control the structures and construct the target molecules with desired properties [14], owing to temperature, pH value and solvent will also affect the structure of resulting crystals [15,16]. Among the numerous organic ligands, pyrazole carboxylate ligands obtained widely concern due to possessing N-donors in pyrazole ring and O atoms on the carboxylate which can provide potential coordination nodes and can exhibit flexible chelating and bridging coordination modes [17,18].…”
