EPR of High‐Spin Co(II) in Fully‐Chelated Octahedral Environments: From Solid State to Frozen Solution

European Journal of Inorganic Chemistry
We present an X‐band EPR and density functional theory (DFT) study of five fully‐chelated Co(II)complexes, in order to assess the differences in their solid state and frozen solution EPR, and to examine the accuracy of the DFT‐predicted EPR parameters. The complexes represent two meridional bis

Structure and ionic conductivity in lithium garnets [PDF]

, 2010
Garnets are capable of accommodating an excess of lithium cations beyond that normally found in this prototypical structure. This excess lithium is found in a mixture of coordination environments with considerable positional and occupational disorder and

Nomenclature of the hydrotalcite supergroup: Natural layered double hydroxides [PDF]

, 2012
Layered double hydroxide (LDH) compounds are characterized by structures in which layers with a brucite-like structure carry a net positive charge, usually due to the partial substitution of trivalent octahedrally coordinated cations for divalent cations,

trans-K3[TcO2(CN)4]

Acta Crystallographica Section E, 2010
The structure of the title compound, tripotassium trans-tetracyanidodioxidotechnetate(V), is isotypic with its Re analogue. The [TcO2(CN)4]3− trans-tetracyanidodioxidotechnetate anion has a slightly distorted octahedral configuration.
