چکیده
Abstract Although sufficient tolerance against attack by superoxide radicals (O 2 − ) has been mainly recognized as an important property for Li–O battery (LOB) electrolytes, recent evidence revealed that other critical factors also govern the cyclability, prompting a reconsideration of basic design guidelines LOB electrolytes. Here, we found LOBs equipped with N , N‐ dimethylacetamide (DMA)‐based electrolyte exhibited better cyclability compared standard This superior is attributable to capabilities quenching 1 O and forming highly decomposable Li . The capability equivalent tetraglyme‐based containing several millimolar concentration typical chemical quencher. Based on these overlooked factors, DMA‐based led despite its lower tolerance. Thus, present work provides novel guideline development

In the title compound, [CaCs2(C2O4)2(H2O)4] n , the Ca(2+) ion, lying on a twofold rotation axis, is coordinated by four O atoms from two oxalate ligands and two bridging water mol-ecules in an octa-hedral geometry. The Cs(+) ion is coordinated by seven O atoms from six oxalate ligands, one bridging water and one terminal water mol-ecule. The oxalate ligand displays a scarce high denticity. The...

In the title complex, [Pr(2)(C(2)O(4))(3)(H(2)O)(4)](n), the two independent Pr(III) ions are both nine-coordinated in a distorted monocapped square-anti-prismatic geometry by seven O atoms from four oxalate ligands and two water mol-ecules. The Pr(III) ions are bridged by the oxalate ligands, forming a layer parallel to (001). O-H⋯O hydrogen bonds connect the layers.

The structure of the title compound, [Cu4(CH3O)4(C11H13O2)4], consists of dimeric dinuclear copper(II) complexes oriented around a centre of inversion. Within each dinuclear fragment, the two Cu(II) atoms are in a distorted square-planar coordination sphere. Two neighbouring fragments are linked by four apical Cu-O contacts, yielding an overall square-pyramidal coordination environment for each...
