Abstract

The synthesis, characterisation and properties of manganese(II) complexes from a pentadentate ligand (L) and pseudohalide anions having composition [MnL(X)](ClO₄), where X = NCS (<b style="mso-bidi-font-weight:normal">1</b>), X = N₃ (<b style="mso-bidi-font-weight:normal">2</b>) and X = NCO (<b style="mso-bidi-font-weight:normal">3</b>), is described. The structure of <b style="mso-bidi-font-weight:normal">1</b> has been determined by single crystal X-ray diffraction studies. The structure determination reveals that the manganese atom is hexacoordinated with an unusual distortion in the coordination sphere of this type of linear pentadentate ligand and thiocyanato anion acts as a terminal donor.
