US 2026/0229257 A1 · Cationic Multimetallic Transition Metal Complexes Salts As Oxygen Releaser In Hard Disk Drives

Abstract

The present disclosure is generally directed towards a data storage device comprising a crystalline salt configured to release oxygen. The crystalline salt comprises a cation and a counteranion. The counteranion may be selected from the group consisting of: ClO4—, PF6—, BF4—, CF3SO3—, and NO3—. In one embodiment, the cation is ([(2-pyridylmethyl)aminomethyl)-4-tert-butylphenolato)M2(O2)(R1)m]2m+)n, where M is selected from the group consisting of: Co, Ni, Mn, Fe, and Cu, and R1 is caboxylated and selected from the electron donating or drawing group consisting of: F, Cl, Br, I, carbonyl, carboxyl, hydroxyl, alkyl, aryl, amine, amide, and nitro. In the cation, n is a numeral between 0 and 4, and m is a numeral between 1 and 100, where m represents the number of repeating units of the cation. The crystalline salt is configured to release oxygen above about 30° C. to maintain a level of about 8% to about 12% of oxygen.
