Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The title complex, [NaNi(C₅H₇O₂)₃]_{<italic>n</italic>}, contains an anionic tris(acetylacetonato)nickelate(II) unit, [Ni(acac)₃]⁻ (acac is acetylacetonate), with a highly regular octahedral coordination geometry. The Ni^II cation lies on a Wyckoff <italic>a</italic> site, resulting in <italic>D</italic>₃ symmetry of the anion. Charge balance is provided by sodium cations, which occupy Wyckoff type <italic>b</italic> sites. Each sodium cation is surrounded by two [Ni(acac)₃]⁻ anions, each of which is connected to the alkali metal through three O atoms, in a <italic>fac</italic> configuration. This arrangement leads to the formation of linear [Na{Ni(acac)₃}]_{<italic>n</italic>} chains along the <italic>c</italic> axis. The Ni...Na distance is 2.9211 (10) Å. The title complex is one of the few examples of heterometallic systems based on alkali and transition metal cations bridged by acetylacetonate ligands.</p> </abstract>
