The corresponding compound of CAS 15629-92-2 is [1,3-Bis(Diphenylphosphino)Propane]Nickel(II) Chloride, which is a metal organic complex with a molecular formula of C₂₇H₂₆Cl₂NiP₂ and a molecular weight of 542.05 g/mol. It is a red to reddish brown powder or crystal, sensitive to air and moisture, and needs to be stored in an inert gas environment.

The melting point of [1,3-Bis(Diphenylphosphino)Propane]Nickel(II) Chloride is 213 degree (decomposition), insoluble in water, soluble in organic solvents such as tetrahydrofuran and dichloromethane, stable to water under neutral conditions, but may react with strong oxidants.

1. It has a four-coordinated distorted tetrahedral structure, with the nickel (II) center coordinated by two chloride ions and two phosphine ligands. It is soluble in polar organic solvents and slightly soluble in water.
2. The compound is stable in a dry and oxygen-free environment and can be operated in the air for a short time, but long-term exposure to air and moisture may cause decomposition or oxidation.

[1,3-Bis(Diphenylphosphino)Propane]Nickel(II) Chloride is a highly efficient catalyst for a variety of organic reactions:
Cross-coupling reactions: such as Suzuki-Miyaura reaction (coupling of aryl halides with aryl boronic acids), Kumada reaction (coupling of Grignard reagents with halogenated hydrocarbons);
Olefin conversion: used for (E)-selective semihydrogenation of internal alkynes, conversion of enol ethers and vinyl sulfides to olefins;
Polymerization reactions: catalyzing the synthesis of polythiophene block copolymers, poly(3-alkoxythiophene), and transfer polycondensation of conjugated polymers;
