A Luminescent and Magnetic Cyano-Bridged Tb³⁺−Mo⁵⁺ Coordination Polymer:  toward Multifunctional Materials

Abstract

A new cyano-bridged coordination polymer network Tb(H2O)5-[Mo(CN)8] was obtained and characterized. This compound has a two-dimensional layered structure and presents luminescence along with a magnetic transition at low temperature.

Synthesis, crystal structure, and physicochemical properties of the new metal-organic framework — the iron(iii) complex with benzene-1,3,5-tricarboxylate

“…In attempting to reproduce the earlier described 14 procedure for the synthesis of the MOF [Fe 2 (H 2 O) 2 (btc) 4/3 ]Cl (2) by the reaction of anhydrous iron chloride with trimesic acid in dimethylformamide in the presence of triethylenedi amine (as a base), we isolated a new coordination compound of the composition [Fe III 2 (OH) 0.3 (H 2 O) 1.7 (btc) 4/3 ]Cl 1.7 • •2.8DMF•1.9H 2 O (1). Compounds 1 and 2 were synthe sized using the reagents and solvents in equal molar ratios.…”

Photoluminescent Porous Modular Lanthanide–Vanadium–Organic Frameworks

“…(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009) design and preparation of novel MOF materials [10] assembled from lanthanide cations [11][12][13][14] and organic ligands containing carboxylate [11] or phosphonate [12,13] binding groups. The latter mimic the tetrahedral geometry of the building units of zeolites and may also direct the formation of highly robust frameworks.…”

“…Recently, the design and synthesis of multifunctional materials with lanthanide octacyanometalate-based metal assemblies are attracting much more interest (Chelebaeva et al, 2008;Przychodzeń et al, 2007;Ikeda et al, 2005;Kosaka et al, 2007;Matoga et al, 2005;Wang et al, 2006). The combination of the octacyanometalate [M(CN) 8 ] 3-/4-(M = Mo,W) building blocks with the lanthanide ions plays an important part in the construction of new supramolecular magnetic materials (Prins et al, 2007).…”
