Magneto-structural correlation of hexakis-dmso cobalt(ii) complex.

ABSTRACT

The magnetostructural correlation of the hexakis-dmso cobalt(ii) complex, [Co(dmso)6](BPh4)2 (dmso dimethylsulfoxide), was investigated by single-crystal X-ray diffraction study and magnetic measurements. The magnetic analysis concluded the negative Δ value (H = Δ(L - 2/3) + E(L - L) - (3/2)κλL·S + ß[-(3/2)κLu + geSu]·Hu (u = x, y, z)), and this was explained by the tetragonal elongation of the octahedral geometry. The magnetostructural correlation was ascertained by both the angular overlap model calculation and the density functional theory calculation.
