The present invention provides a process for preparing a water splitting catalyst containing [Mn.sub.4CaO.sub.4] core structure and use thereof. The present invention provides clusters containing [Mn.sub.4CaO.sub.4] core structure by a chemical synthesis using inexpensive metal ions (Mn.sup.2+, Ca.sup.2+ ions), simple carboxyl ligands and a permanganate, performed single crystal X-ray diffraction on their space structure, and characterized their physical and chemical properties with electron spectrum, electrochemical and electron paramagnetic resonance technologies and the like. These compounds can catalyze water splitting in the presence of oxidant to release oxygen and can also catalyze water splitting on the surface of an electrode to release electrons onto the surface of the electrode to form a current.

Phosphine phosphonate and phenoxyphosphine ligands bearing polyethylene glycol (PEG) chains are used as described herein to produce heterobimetallic catalysts. The ligands can be metallated selectively with palladium or nickel and secondary metal ions to provide well-defined heterobimetallic compounds. These heterobimetallic complexes exhibit accelerated reaction rates and greater thermal stability in olefin polymerization compared to other catalysts.

A highly active hydroprocessing catalyst that comprises an inorganic oxide support particle having been impregnated with a metals-impregnation solution comprising a complexing agent and a hydrogenation metal that is further incorporated with an organic additive blend.

Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers. MOFs having ambient condition stability may comprise a plurality of metal clusters comprising one or more M.sub.4O clusters (M is a metal), and a plurality of 4-pyrazolecarboxylate ligands coordinated to the plurality of metal clusters to define an at least partially crystalline network structure having a plurality of internal pores. The MOFs may have a Pa3 symmetry, which upon activation may convert into Fm3m symmetry. Methods for synthesizing the MOFs may comprise combining a metal source, such as a preformed metal cluster, with 4-pyrazolecarboxylic acid, and reacting the preformed metal cluster with the 4-pyrazolecarboxylic acid to form a MOF having an at least partially crystalline network structure with a plurality of internal pores defined therein and comprising a plurality of metal clusters coordinated to a multidentate organic ligand comprising 4-pyrazolecarboxylate.

In one aspect, phosphine compounds comprising three adamantyl moieties (PAd.sub.3) and associated synthetic routes are described herein. Each adamantyl moiety may be the same or different. For example, each adamantyl moiety (Ad) attached to the phosphorus atom can be independently selected from the group consisting of adamantane, diamantane, triamantane and derivatives thereof. Transition metal complexes comprising PAd.sub.3 ligands are also provided for catalytic synthesis including catalytic cross-coupling reactions.
