Abstract:
Conjugated metal dicarboxylates show promising properties as rechargeable battery anode materials; however, the structures of reduced (discharged) phases remain elusive. Here, we use chemical lithiation to solve the crystal structures of two tetralithium dicarboxylates for the first time. The structures are identical to those formed by electrochemical lithiation in coin cells. Solid-state NMR and DFT calculations show that there is complete mixing of Li cations upon intercalation into the structure.

02:46Crystal Field Theory - Tetrahedral and Square Planar Complexes
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,...

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...
