摘要:
                                Pentacoordinate Co(II) complexes possessing the {CoN3X2) chromophore (X = Cl, O) have been synthesized and structurally characterized. The magnetic data confirm high magnetic anisotropy expressed through the axial zero-field splitting parameter D/hc = 50-70 cm(-1). These values lie between those found in tetracoordinate and hexacoordinate Co(II) complexes. (C) 2013 Elsevier Ltd. All rights reserved.
