Organic materials are increasingly commanding attention as a sustainable choice for charge storage in rechargeable batteries. To fully realise their promise, significantly more understanding is needed in terms of structure-property correlations. Here we report a highly conjugated molecule, disodium anthracene-9,10-carboxylate (Na2ADC), synthesised using rapid microwave-assisted heating and evaluated as an anode material in sodium-ion batteries. Detailed material characterisation is reported, including the crystal structure determined from three-dimensional electron diffraction (3D ED) studies, demonstrating the suitability and advantage of this method for the structural characterisation of organic electrode materials. This study highlights the role of molecular design and structural properties in facilitating the delivery of high-performing organic electrode materials.

02:42Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
02:58Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
