Abstract
- Rare examples of trinuclear [Ni–N<subscript>2</subscript>–M–N<subscript>2</subscript>–Ni] core (M = Ca, Mg) with linear bridged dinitrogen ligands are reported in this work. The reduction of [<superscript>i</superscript>Pr<subscript>2</subscript>NN]Ni(μ-Br)<subscript>2</subscript>Li(thf)<subscript>2</subscript> (1) (<superscript>i</superscript>Pr<subscript>2</subscript>NN = 2,4-bis-(2,6-diisopropylphenylimido)pentyl) with elemental Mg or Ca in THF under an atmosphere of dinitrogen yields the complex {<superscript>i</superscript>Pr<subscript>2</subscript>NNNi(μ-N<subscript>2</subscript>)}<subscript>2</subscript>M (thf)<subscript>4</subscript> (M = Mg, complex 2 and M = Ca, complex 3). The bridging end-on (μ-N<subscript>2</subscript>)<subscript>2</subscript>M(thf)<subscript>4</subscript> moiety connects the two [<superscript>i</superscript>Pr<subscript>2</subscript>NNNi]<superscript>−</superscript> nickelate fragments. A combination of X-ray crystallography, solution and solid-state spectroscopy have been applied to characterize complexes 2 and 3, and DFT studies have been used to help explain the bonding and electronic structure in these unique Ni–N<subscript>2</subscript>–Mg and Ni–N<subscript>2</subscript>–Ca complexes.
