Accessing water processable cyanido bridged chiral heterobimetallic Co(ii)–Fe(iii) one dimensional network

Abstract

A water processable cyanido bridged extended chiral heterobimetallic Co(II)-Fe(III) network is assembled. The unusual water processability of the coordination polymer originate from dangling hydrophilic substituents. The present approach offers a...

Magnetic anisotropy of transition metal and lanthanide ions in pentagonal bipyramidal geometry

“…This compound has ferroelectric properties and can be processed in an aqueous medium. 97 Discrete heterometallic complexes in which Co II is exchange coupled with another metal ion have also been reported. These comprise the pentanuclear complexes [{Co(H 2 L1 Ph )} 3 {M(CN) 6 } 2 ] (M = Cr III or Fe III ), 98 and [{Co(H 2 L1 R )} 3 {W(CN) 8 } 2 ] with R = Ph, BiPh (Fig.…”

Influence of the Capping Ligands on the Self‐Assembly of Cyanido‐Bridged Mn(II)‐Fe(III) Aggregates: Synthesis, Crystal Structures, Electrochemical and Magnetic Properties

“…Introduction of capping ligands reasonably affects the solubility as well as steric effects in cyanido bridged architectures. [27] In this regard, tricyanidometallate building blocks have emerged as one of the most versatile precursors for designing PBAs and so far led to the controlled fabrication of various desirable magnetic architectures. [16] The nature of blocking ligand used for the metallic node, relative disposition (facial or meridional) of the cyanido ligands as well as the charge on the cyanidometallate precursor have profound influence in the structure and topology of the resulting cyanido bridged architectures.…”

“…Cyanometallate linkers, [LM(CN) n ] x− incorporating suitable blocking ligand L gave access to wide range of cyanido bridged architectures mimicking structural fragments observed in PBAs. Introduction of capping ligands reasonably affects the solubility as well as steric effects in cyanido bridged architectures [27] . In this regard, tricyanidometallate building blocks have emerged as one of the most versatile precursors for designing PBAs and so far led to the controlled fabrication of various desirable magnetic architectures [16] .…”

[MII(H2dapsc)]-[Cr(CN)6] (M = Mn, Co) Chain and Trimer Complexes: Synthesis, Crystal Structure, Non-Covalent Interactions and Magnetic Properties

“…The presence of labile ligands in the axial positions of the PBP complexes makes them attractive building blocks for the construction of low-dimensional heteronuclear compounds by replacing these ligands with bridging cyanometallates or the PBP complexes with cyanide apical groups [ 17 , 23 , 24 , 37 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 ]. Up to date, tri-, penta-, and decanuclear SMMs and coordination polymeric SCMs have been obtained along the way.…”
