Abstract: The Ni atom in the title complex, [Ni(C₂H₃O₂)₂(C₁₅H₁₃N₅)] or [Ni(CH₃COO)₂(tpdaH2)] (tpdaH2 is tripyridyldiamine), has a distorted octahedral coordination geometry formed by the tridentate tpdaH2 ligand and two acetate groups. The tpdaH2 ligand is mer-coordinated, with the N atom of the central pyridine ring in the equatorial position and the N atoms of the peripheral pyridine rings in the axial positions. The remaining three equatorial positions are occupied by the O atoms of two acetate anions. The H atoms of both NH groups of the tpdaH2 ligand are involved in strong hydrogen bonds with O atoms of adjacent complex molecules to form a three-dimensional network.
