Abstract: The title mononuclear complex, [Ni(C₂H₃O₂)₂(C₃H₄N₂)₄], has been prepared and characterized by X-ray structure analysis. The molecule contains a six-coordinate Ni^II atom displaying distorted octahedral coordination geometry defined by the four pyrazole N atoms in the equatorial plane and two O atoms of the carboxylate groups in trans-apical positions. The Ni-N(pyrazole) distances range from 2.074 (2) to 2.097 (2) Å and the Ni-O(acetate) distances are 2.060 (2) and 2.072 (2) Å.
