The invention discloses an economic and safe synthesis method of a zero-valent nickel coordination compound, and relates to the technical field of medical catalysis. The structural formula of the zero-valent nickel coordination compound is NiRn, wherein the valence state of Ni is zero, R is a coordination ligand, n is the coordination number. The synthesis method comprises the following steps: adding tetrahydrofuran, nickel chloride hexahydrate and the coordination ligand to a reactor, stirring to react under the protection of inert gas, adding a molecular sieve, heating, stirring to react, cooling, adding zinc powder, and stirring to react; and after the reaction is finished, filtering the reaction system under the protection of inert gas, drying in vacuum to remove the organic solvent, washing, recrystallizing, and drying in vacuum to obtain the product. The method has the advantages of simple process operation, cheap and easily available raw materials, safe and stable reaction, highefficiency, high yield and high purity, and can be used for preparing several common zero-valent nickel coordination compounds.
