An organic frame material having zinc containing isopoly-molybdic acid metal, a method of manufacturing the same, and the application thereof are provided. The organic frame material having zinc containing isopoly-molybdic acid metal includes a three-dimensional network structure in which the zinc ions coordinate with 2,3,5,6-tetrafluoro-bis (1,2,4-triazole-1-methyl) benzene ligands and trinuclear molybdate anions. The organic frame material having zinc containing isopoly-molybdic acid metal exhibits high catalytic activity, thermal stability, low toxicity, ease of synthetization and use, and strong reproducibility.

The invention relates to oligomerization of olefins, such as ethylene, to higher olefins, such as a mixture of 1-hexene and 1-octene, using a catalyst system that comprises a) a source of chromium b) one or more activators and c) a phosphacycle-containing ligating compound. Additionally, the invention relates to a phosphacycle-containing ligating compound and a process for making said compound.

A molecular-spin qubit is formed from a coordination complex having a plurality of strong-field ligands bound to a metal-atom center. The ground state has non-zero spin, and the resulting ground-state magnetic sublevels are separated by microwave or millimeter-wave frequencies, even in the absence of an external field. Two of these sublevels may be used as a quantum resource for quantum information processing, quantum communication, quantum memory, sensing, and other applications. Optical pumping to an excited state may be used to spin-polarize the molecular-spin qubit, and to measure its population by detecting photoluminescence. The energy-level structure of the metal-atom center can be modified due to its interaction with the ligands, therefore allowing the molecular-spin qubit to be “chemically tuned” based on the number and type of ligands. Ensembles of these molecular-spin qubits can be controllably deposited on a surface, or otherwise integrated into devices and structures.

Molybdenum(0) coordination complexes comprising an arene ligand and one or more neutral ligands which coordinate to the metal center by carbon, nitrogen or phosphorous are described. Methods for depositing molybdenum-containing films on a substrate are described. The substrate is exposed to a molybdenum precursor and a reactant to form the molybdenum-containing film (e.g., elemental molybdenum, molybdenum oxide, molybdenum carbide, molybdenum silicide, molybdenum nitride). The exposures can be sequential or simultaneous.

The invention relates to Schrock-alkylidene complexes comprising a phenanthroline ligand. The complexes may dissociate when subjected to a solvent and release the complex being catalytically active in an olefinic metathesis reaction without needing a Lewis acid such as zinc chloride for removing the ligand. Thus, the phenanthroline complexes are autoactivating.
