•Five [CoX2L2] complexes were investigated by magnetometry.•The zero-field splitting parameter varies as D/hc = − 13 to + 5 cm− 1;•D-parameter correlates with the angular deformation parameter.
Five tetracoordinate cobalt(II) complexes of the formula [CoX2L2] have been investigated by SQUID magnetometry; X is the (pseudo)halide ligand and L is the N- or P-donor ligand. The complexes exhibit a moderate magnetic anisotropy expressed by the zero-field splitting parameter D. Its value ranges as D/hc = −13 to + 5 cm 21 −1. The value of the D-parameter increases with the angular deformation δ that measures a deviation of the X–Co–X and L–Co–L angles with respect to the ideal tetrahedron.
Graphical abstractZero-field splitting parameter D was determined by analyzing the SQUID-magnetometric data for five tetracoordinate cobalt(II) complexes of the formula [CoX2L2]. It ranges as D/hc = − 13 to + 5 cm−1 and correlates with the angular deformation parameter d that measures a deviation with respect to the ideal tetrahedron.Figure optionsDownload full-size imageDownload as PowerPoint slide
