A Decade of Octacyanides in Polynuclear Molecular Materials

Abstract

The aim and the scope of this review is to show the results of ten years of research following the first reports on magnetic and photomagnetic assemblies constructed from. It is illustrated on the basis of our own work as well as a wide range of studies carried out in numerous laboratories around the world. The diversity and evolution of topological and structural patterns is discussed alongside synthetic strategies, which led to the establishment of regular magnetostructural correlations in selected 3D systems. Different types of functionality observed in solid phases are presented with special attention devoted to tuning of magnetic

Syntheses, Structures, and Magnetic Properties of Three Manganese(II)-Octacyanotungstate(V) Bimetallic Compounds with Linear Ligands

“…17 However, how to control rationally the desired structures with specific properties still remains a great challenge. In order to search for effective synthetic strategies of high-dimensional octacyanometallate-based compounds, and then further investigate the structure-magnetism correlations involved in such systems, the in situ and secondary assembly methods were employed recently by our group in the presence of linear bridging ligands dpe and 4,4′-azopyridine (azpy), isolating three manganese(II)-octacyanotungstate(V) bimetallic compounds with 1D or 3D structures: [Mn-(H 2 O) 2 (dpe)] 3 ■ EXPERIMENTAL SECTION General Considerations. All chemicals and solvents were purchase from Alfa Aesar and used as received.…”

Neutral Low-Dimensional Assemblies of a Mn(III) Schiff Base Complex and Octacyanotungstate(V): Synthesis, Characterization, and Magnetic Properties

“…Some of them are 1D polymers [53][54][55][56]; others possess layered [57][58][59][60][61][62][63] or 3D network structures [64][65][66][67][68]. The paramagnetic cyanotungstate(V) tectones have been used to build discrete molecules [69][70][71], chains [53][54][55][56], 2D [57] and 3D networks [64][65][66][67][68], and some of them have displayed variable magnetic properties such as high ordering temperatures [72], photo-induced magnetism [73,74], SMMs [75], and SCMs [17,54,55]. However, the assemblies of the paramagnetic [W(CN) 8 ] 3− precursor and manganese(III) Schiff base complex, [Mn(SB)] + , are fairly limited and poorly studied in comparison with the large family of bimetallic compounds comprised of the [Mn(SB)] + cation and the 3d metal hexacyanides that are extensively investigated both structurally and magnetically [76].…”

Synthesis, Crystal Structure and Magnetic Properties of Three {CrIIIMnII} Heterodimetallic Complexes Based on Heteroleptic Cyanido‐Bearing CrIII Building Blocks

“…The short, divergent cyanido ligand is able to connect two different metal ions and to efficiently mediate magnetic interactions between paramagnetic metal ions. Homoleptic dia‐ and paramagnetic cyanido‐containing metalloligands, [M III (CN) 6 ] 3– (M = Cr, Fe and Co),[1a], [1b], and [M IV/V (CN) 8 ] 4–/3– (M = Mo and W), are widely used for constructing coordination polymers. Their heteroleptic counterparts [M III (L)(CN) x ] – [M = Cr, Fe and Co; L = bi‐ ( x = 4) or tridentate ( x = 3) ligand], [Fe III (L′) y (CN) 2 ] – [L′ = 1,2‐bis(pyridine‐2‐carboxamido)benzenate (bpb 2– , y = 1), N , N′ ‐ethylenebis(salicylideneiminate) (salen 2– , y = 1), semibenzoquinonediiminate (s‐bqdi, y = 2) and 2,2′‐bipyridine (bpy, y = 2)] and [W IV/V (bpy)(CN) 6 ] 2–/–[24] contain a smaller number of cyanido groups and negative charge, which give rise to different topologies, and usually, lower dimensionality, of the resulting heterometallic complexes.…”
