In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Magnetic properties of new layered compounds LaM1/3Sb5/3O6, M = Co, Ni, and Cu, with a honeycomb structure, published in 2021-12-31, which mentions a compound: 12069-69-1, mainly applied to lanthanum cobalt antimony oxide layered compound magnetic property, Computed Properties of CH2Cu2O5.
New compounds with the rosiaite type structure LaM1/3Sb5/3O6, M = Co, Ni, and Cu, were synthesized. The compounds belong to quasi-two-dimensional magnets, in which magnetic interactions occur in the layers with a honeycomb structure. It is shown that there is no long-range magnetic order in these compounds The temperature and field dependences of the magnetization in the compounds with M = Co, Ni indicate the presence of short-range anti-ferromagnetic and ferromagnetic exchange interactions. In the LaM1/3Sb5/3O6, M = Co, Ni, compounds, the interactions occur between Co2+ or Ni2+ ions of isolated magnetic clusters randomly distributed in the paramagnetic matrix in the chains of (M/Sb)O6 octahedrons. These clusters have sizes comparable with the crystal cell size. The LaCu1/3Sb5/3O6 compound is paramagnetic.
When you point to this article, it is believed that you are also very interested in this compound(12069-69-1)Computed Properties of CH2Cu2O5 and due to space limitations, I can only present the most important information.
