Abstract
Nickel-metal-containing solids for use in manufacturing nickel metal complexes are disclosed. The nickel-metal-containing solids are made by reducing basic nickel carbonates. By varying the molar ratios of carbonates and bicarbonates to nickel salts, the methods provide basic nickel carbonates that produce superior nickel metal-containing solids that react more effectively with phosphorous-containing ligands. The phosphorous containing ligands can be both monodentate and bidentate phosphorous-containing ligands.
