Synthesis of Geminal Bis‐ and Tetrakisphosphonate Ester Derivatives and Their Coordination Behavior Towards Ca(II) Ions

European Journal of Inorganic Chemistry, Volume 2022, Issue 17, June 17, 2022., 2022
Geminal Bisphosphonate (BP) Esters in Ca(II) Ion Coordination. A series of geminal BPs was prepared starting from their corresponding ethyl‐ or isopropyl (arylmethylene)phosphonate ester precursors. Complexation with CaCl2 yields the derived coordination compounds [Ca(H2O)2(L1–L3)2]Cl2 or [Ca(L8)Cl2]n.

The Pivotal Role of s‐, p‐, and f‐Block Metals in Water Electrolysis: Status Quo and Perspectives

Advanced Materials, Volume 34, Issue 18, May 5, 2022., 2022
This review pioneeringly presents the unique and essential role of some s‐, p‐, and f‐block metal species enabling transition metal‐based electrocatalysts to efficiently drive hydrogen evolution and oxygen evolution reaction. Abstract Transition metals, in particular noble metals, are the most common species in metal‐mediated water electrolysis because

Tracing the Jahn‐Teller Distortion of C60n− in Isostructural Fullerides [M(NH3)7]C60 ⋅ NH3, M=Ba, Sr, K

Zeitschrift für anorganische und allgemeine Chemie, Volume 647, Issue 11, Page 1132-1138, June 11, 2021., 2021
Abstract Single crystals of new [Sr(NH3)7]C60 ⋅ NH3 (compound 1) and [K(NH3)7]C60 ⋅ NH3 (compound 2) were prepared by extracting mixtures of potassium and C60 with liquid ammonia, where for the synthesis of 1 solid strontium chloride was added to the extraction mixture.

Ternary erbium chromium sulfides : structural relationships and magnetic properties [PDF]

, 2009
Single crystals of four erbium-chromium sulfides have been grown by chemical vapor transport using iodine as the transporting agent. Single-crystal X-ray diffraction reveals that in Er(3)CrS(6) octahedral sites are occupied exclusively by Cr(3+) cations,

New Crystal Structures of Rare‐Earth Metal(III) Oxotellurates(IV) RE2Te3O9: A1‐Type (RE=La, Ce) and A2‐Type (RE=Pr, Nd)

Zeitschrift für anorganische und allgemeine Chemie, Volume 647, Issue 2-3, Page 134-150, February 11, 2021., 2021
Abstract The new rare‐earth metal(III) oxotellurates(IV) RE2Te3O9 (RE=La−Nd) of the so far unknown A‐type structure can be obtained as needle‐shaped single crystals through solid‐state reactions of the corresponding binary oxides. Their crystal structures were determined as A1‐type for RE=La and Ce or A2‐type for RE=Pr and Nd by single‐crystal X‐ray ...

Co-ordination behaviour of a novel tristhiourea tripodal ligand; structural variations in a series of transition metal complexes [PDF]

, 2016
The co-ordination chemistry of a tristhiourea tris(2-pyridylmethyl)amine ligand (L1) with a series of transition metal ions has been investigated. Crystallographic data show that large metal ions, with no geometrical preferences , such as Mn(II) and Cd ...

[2-(3,5-Dimethyl-1H-pyrazol-1-yl-κN2)-1,10-phenanthroline-κ2N,N′]bis(nitrito-κ2O,O′)cadmium(II)

Acta Crystallographica Section E, 2010
In the title complex, [Cd(NO2)2(C17H14N4)], the CdII ion assumes a distorted monocapped octahedral coordination geometry defined by an N3O4 donor set. The crystal structure is stabilized by π–π stacking interactions [shortest ...
