Custom Coordination Environments for Lanthanoids: Tripodal Ligands Achieve Near-Perfect Octahedral Coordination for Two Dysprosium-Based Molecular Nanomagnets [PDF]
Inorganic Chemistry, 2017 Controlling the coordination sphere of lanthanoid complexes is a challenging critical step toward controlling their relaxation properties. Here we present the synthesis of hexacoordinated dysprosium single-molecule magnets, where tripodal ligands achieve

High- versus Low-Spin Ni2+ in Elongated Octahedral Environments: Sr2NiO2Cu2Se2, Sr2NiO2Cu2S2, and Sr2NiO2Cu2(Se1-x S x )2. [PDF]
Chem Mater, 2022 Sr2NiO2Cu2Se2, comprising alternating [Sr2NiO2]2+ and [Cu2Se2]2- layers, is reported. Powder neutron diffraction shows that the Ni2+ ions, which are in a highly elongated NiO4Se2 environment with D4h symmetry, adopt a high-spin configuration and carry localized magnetic moments which order antiferromagnetically below ∼160 K in a √2a × √2a × 2c ...

Mg Environments in the Octahedral Sheet of 2:1 Talc‐Like Hybrid Phyllosilicates: A Comparative XAFS Study [PDF]
European Journal of Inorganic Chemistry, 2010 AbstractPhenethyl and Phenylaminomethyl talc‐like hybrid (TLH) materials prepared by a one‐step synthetic procedure are investigated by Mg K‐edge X‐ray absorption fine structure (XAFS) to obtain structural information on the octahedral sheet of these 2:1 phyllosilicates.

LOW TEMPERATURE PARAMAGNETIC PROPERTIES OF CU2+ AND TI3+ IN OCTAHEDRAL ENVIRONMENTS
Le Journal de Physique Colloques, 1971 E. P. R. and spin-lattice relaxation rates measured below 4.2 °K indicate the presence of a Jahn-Teller effect. For Cu2+ in Lanthanum Magnesium nitrate a Direct process is observed, the rate of which is five orders of magnitude faster than for the same ion in a Tutton salt. For Ti3+ in Methyl Ammonium alum the g values, g⊥ = 1.37 ± 0.01, g|| = 1.61 ± 0.

Octahedral Hexachloro Environment of Dy3+ with Slow Magnetic Relaxation and Luminescent Properties [PDF]
European Journal of Inorganic Chemistry, 2021 AbstractThe compound [BiCNIm]3[DyCl6] was synthesized from a nitrile‐functionalized imidazolium ionic liquid [BiCNIm][Cl] and DyCl3 ⋅ 6H2O in acetonitrile using solvothermal conditions. Structural characterization reveals that the Dy3+ ions are in a quasi‐regular octahedral environment, formed by six chloride anions.

Nitrogen Dioxide Selective Sensor for Humid Environments Based on Octahedral Indium Oxide [PDF]
Frontiers in Sensors, 2021 We report the growth of micrometer-sized In2O3 octahedral structures, which are next aligned in chains using dielectrophoresis on top of microhotplates with prepatterned electrodes and integrated heater to work as chemoresistive gas sensors. The devices are relatively fast (180 s), highly sensitive (response up to ~256%), and selective toward NO2 in ...

Magneto-Structural Relationship of Tetragonally-Compressed Octahedral Iron(II) Complex Surrounded by a pseudo-S6 Symmetric Hexakis-Dimethylsulfoxide Environment [PDF]
Magnetochemistry, 2021 Since the octahedral high-spin iron(II) complex has the 5T2g ground term, the spin-orbit coupling should be considered in magnetic analysis; however, such treatment is rarely seen in recent papers, although the symmetry-sensitive property is of interest to investigate in detail.

Atoms in Highly Symmetric Environments: H in Rhodium and Cobalt Cages, H in an Octahedral Hole in MgO, and Metal Atoms Ca-Zn in C20 Fullerenes [PDF]
Symmetry, 2021 An atom trapped in a crystal vacancy, a metal cage, or a fullerene might have many immediate neighbors. Then, the familiar concept of valency or even coordination number seems inadequate to describe the environment of that atom. This difficulty in terminology is illustrated here by four systems: H atoms in tetragonal-pyramidal rhodium cages, H atom in ...
