Positive zero-field splitting in a hexacoordinate nickel(II) complex

Novel molecular Ni(II) complex [Ni(H2O)4(2-Me-Snic)2]·4H2O has been synthesized and structurally characterized. It refers to an elongated tetragonal bipyramid for which a positive zero-field splitting is confirmed by magnetometry. The complex matches the magnetostructural D-correlation for hexacoord...

Description
Summary:Novel molecular Ni(II) complex [Ni(H2O)4(2-Me-Snic)2]·4H2O has been synthesized and structurally characterized. It refers to an elongated tetragonal bipyramid for which a positive zero-field splitting is confirmed by magnetometry. The complex matches the magnetostructural D-correlation for hexacoordinate Ni(II) complexes with moderate structural and magnetic anisotropy Dstr=+8.60pm, Dmag=+4.39cm−1. Novel molecular Ni(II) complex [Ni(H2O)4(2-Me-Snic)2]·4H2O refers to an elongated tetragonal bipyramid for which a positive zero-field splitting is confirmed by magnetometry. The complex matches the magnetostructural D-correlation for hexacoordinate Ni(II) complexes with moderate structural and magnetic anisotropy. [Display omitted] •Nickel(II) complex with 2-methyl-sulfanyl-nicotinic acid ligand was synthesized.•The chromophore refers to an elongated bipyramid with positive D-value.•The magnetostructural D-correlation possesses predictive character.
