Safety of Bis(2,2,6,6-tetramethyl-3,5-heptanedionato)nickel(II). The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Bis(2,2,6,6-tetramethyl-3,5-heptanedionato)nickel(II), is researched, Molecular C22H38NiO4, CAS is 14481-08-4, about Abrupt Switching of Crystal Fields during Formation of Molecular Contacts.

Magnetic mols. have the potential to be used as building blocks for bits in quantum computers. The spin states of the magnetic ion in the mol. can be represented by the effective spin Hamiltonian describing the zero field splitting (ZFS) of the magnetic states. We determined the ZFS of mech. flexible metal-chelate mols. (Co, Ni, and Cu as metal ions) adsorbed on Cu2N/Cu(100) by inelastic tunneling spectroscopy at temperatures down to 30 mK. When moving the tip toward the mol., the tunneling current abruptly jumps to higher values, indicating the sudden deformation of the mol. bridging the tunneling junction. Hand in hand with the formation of the contact, an abrupt change of the ZFS occurs. This work also implies that ZFS expected in mech. break junctions can drastically deviate from that of adsorbed mols. probed by other techniques.
Although many compounds look similar to this compound(14481-08-4)Safety of Bis(2,2,6,6-tetramethyl-3,5-heptanedionato)nickel(II), numerous studies have shown that this compound(SMILES:CC(C)(C1=O[Ni+2]2(O=C(C(C)(C)C)[CH-]1)O=C([CH-]C(C(C)(C)C)=O2)C(C)(C)C)C), has unique advantages.
