Abstract: We prepared a series of isostructural chiral cyanido-bridged zigzag chains [Ln­(tmu)5]­[W­(CN)8] (Ln = Gd, 1; Tb, 2; Dy, 3; Ho, 4; Er, 5; Tm, 6) using achiral tmu = tetramethylurea. Their chiral character was confirmed with single crystal X-ray diffraction and circular dichroism measurements. Magnetic studies show antiferromagnetic interactions within cyanido-bridged LnIII–WV pairs, and interchain ordering of net spins in 1, 4, and 5. It is worth to emphasize that Dy-, Er-, and Tm-based systems combine magneti… Show more

“…The shortest intrachain Ln III ···W V and W V ···W V distances for 1–9 are in the ranges of 5.717(1)–5.794(1) and 10.353(1)–10.502(1) Å, respectively, while the shortest interchain Ln III ···W V and W V ···W V distances are in the ranges of 8.802(1)–8.840(1) and 9.747(1)–9.772(1) Å, respectively. Determined values of bond lengths and angles are comparable to previously described parameters for 1D amide–Ln III –W V chains. In addition, assemblies 1–9 are rare examples of 1D cyanido-bridged coordination polymers without crystallization solvent molecules and hydrogen bond networks . Additionally, these coordination polymers have a pyroelectric crystal structure, capable of generating a temporary current upon heating or cooling, in which the electric polarization is along the b -axis …”

“…Interestingly, detailed analysis of records in the Cambridge Structural Database (CSD) in a search of 1D noncentrosymmetric helical Ln III –[W V (CN) 8 ] systems revealed that all previously known systems were exclusively achieved through the rational design with chiral bisoxazolines [ SS / RR -2,6-bis­[4-isopropyl-2-oxazolin-2-yl]­pyridine, SRSR / RSRS -2,6-bis­[8 H -indeno­[1,2- d ]­oxazolin-2-yl]­pyridine, and SS / RR -2,2′-(2,6-pyridinediyl)­bis­(4-isopropyl-2-oxazoline)] and by spontaneous resolution from achiral ligands ( N , N -dimethylformamide, N , N -dimethylacetamide, and N , N , N ′, N ′-tetramethylurea). , These observations suggest that helical motives in Ln III –[W V (CN) 8 ] systems can be rationally achieved using bulky achiral amides rather than by preparing them from expensive enantiopure ligands.…”

“…The design, synthesis, and characterization of magnetic cyanido-bridged metal assemblies have attracted a lot of attention in materials science, especially Prussian blue analogues offering various functionalities. From the viewpoint of magnetism, the lanthanide-based metal–organic frameworks are an excellent base for the construction of multifunctional magnetic materials since most of the lanthanides reveal intrinsic magnetic and/or luminescence properties. Until now, numerous single-molecule magnets (SMMs) based on Dy III , Tb III , and Er III and much rarer examples of compounds based on Ce III , Nd III , Ho III , Tm III , and Yb III have been reported. It is also well-established that paramagnetic Dy III and Tb III compounds can emit intense and sharp visible (vis) luminescence while complexes with Nd III , Yb III , and Er III can generate near-infrared (NIR) light. These characteristics give a remarkable opportunity to combine magnetism with luminescence and even next to incorporate additional physical properties such as nonlinear optical activity, conductivity, or porosity. ,, In some rare cases, the combination of two or more different physicochemical properties resulted in new cross-effects leading to unique phenomena . This successful approach resulted in the formation of emissive SMMs with tunable light-emitting characteristics for homo- and heterometallic materials, including polycyanidometalate-based systems. , …”
