The impact of ligands upon topology and functionality of octacyanidometallate-based assemblies

Further Insights into the Role of Temperature in the Synthesis of the Lanthanide(III)‐Pyrazine‐Octacyanotungstate(V) System: an Example of Discrete Materials

“…An ion-pair compound 3 was isolated upon changing the lanthanide ions from Ce (or Eu) to Tb, in spite of the same synthetic conditions as compounds 1 and 2. To the best of our knowledge, only one example of octacyanometalatebased lanthanide compounds with ion-pair structures [Tm(terpy)(DMF) 2 (Figure 4). Both the central terbium(III) and tungsten(V) atoms display a slightly distorted square antiprism.…”

“…[1] In particular, octacyanide-bearing precursors [M(CN) 8 ] 3-/4-(M = Mo, W) have been employed usually to construct coordination compounds with unique topologies and promising properties, such as single-molecule or single-chain magnets, photomagnetism, spin-crossover magnetism, luminescence, and so on. [2,3] With respect to synthesis, various strategies have been applied to construct these materials, comprising the direct reactions of precursors, [4][5][6] aids of secondary reagent or assisting molecules or bridging spacers, [7][8][9] employ of clusters, [10] the electrochemical synthesis, [11] and microwave-assisted self-assembly. [12] However, how to control rationally the desired structures of such system with specific properties still remains a great challenge.…”

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

“…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]. To the best of our knowledge, so far only six bimetallic low-dimensional magnetic systems involving [Mn(SB)] + and [W(CN) 8 ] 3− units have been reported [54,55,[69][70][71]77].…”
