Control of magnetic spin states by various mixed anionic ligands in trinickel complexes: Synthesis, crystal structures and physical properties

This study provides an opportunity to control the magnetic spin of nickel atoms using various mixed anionic ligands. A series of linear trinickel complexes supported by two kinds of ligands, oligo-α-pyridylamido and sulfonyl amido/amido, were synthesized and their structures were determined by X-ray diffraction. The three nickel atoms of [Ni3(Lpts) 2(dpa)2] (1) (dpa- = dipyridylamido, Lpts 2- = N,N′-bis(p-toluenesulfonyl)pyridyldiamido) display short Ni-N (～1.90 A) bond distances, which are consistent with a low spin state of Ni(ii) ions, and exhibit spin states of (0, 0, 0) for the three Ni(ii) ions. One of the terminal Ni(ii) ions of [Ni3(Lms) 2(dpa)2(H2O)] (2) (Lms2- = N,N′-bis(4-methylsulfonyl)-pyridyldiamido) and [Ni3(Lpts) 2(pepteaH2)] (4) (pepteaH22- = pentapyridyldiamidodiamine) bonded with an axial ligand exhibits a square pyramidal (NiN4X) geometry with long Ni-N bond distances (～2.10 A) which are consistent with a high spin Ni(ii) configuration. The spin states of these trinickel complexes are (1, 0, 0). Complex 2 and 6 can be interchanged by the removal or addition of an axial water molecule. The structural features of 6 are comparable with those of 1. Both the terminal Ni(ii) ions in [Ni3(LAc)2(dpa)2] (3) (Lac 2- = N,N′-biacetyl-pyridyldiamido) are in square pyramidal geometry and exhibit high spin. The spin states of the nickel ions in 3 are (1, 0, 1), and the two terminal nickel ions exhibit antiferromagnetic interactions. The molecular structure of [Ni3(Lpts)2(dpa) 2](BF4) (5), which was obtained by the one-electron oxidation of 1, is similar to those of the neutral analogue 1, except for the presence of a counter anion to compensate for the positive charge on the Ni 3 core. All of the Ni-Ni bond lengths of 5 are slightly shorter (ca. 0.05 A) than those in the neutral analogues. This is attributed to the formation of partial Ni-Ni bonding. The Royal Society of Chemistry.
