Robust Dirac spin gapless semiconductors in a two-dimensional oxalate based organic honeycomb-kagome lattice

“…complexes have been synthesized. 17–19 Meanwhile, in these compounds, the C–C bond between two carboxylate groups (–COO) promotes the formation of an extended π-system. Such an extended π-conjugated ligand may induce strong d–π hybridization in the framework and thus enhance the overall super-exchange interaction.…”

Solvent dependence of crystal structure and dielectric relaxation in ferromagnetic [MnCr(oxalate)3]− salt

“…For example, when trans-syn-trans -dicyclohexano[18]crown-6 exhibited a flat conformation, the cyclohexane incorporated into the crystal honeycomb holes prevented solvent incorporation. 24,25…”

Stable Ferromagnetic Crystal of Two‐Dimensional Manganese‐Chromium Oxalate with Supramolecular Cation

“…In the course of study, we reported on several crystals of {[Mn II Cr III (oxalate) 3 ] – } with supramolecular cations. Although the {[Mn II Cr III (oxalate) 3 ] – } exhibited various dimensionalities in the crystals, such as 3D cage structures and typical 2D layers, these crystals tend to incorporate crystal solvent in the frameworks. The {[Mn II Cr III (oxalate) 3 ] – } networks have large pores – the size of a typical 2D honeycomb pore is 10–11 Å in diameter , .…”
