Dinuclear manganese(iii) complexes with bioinspired coordination and variable linkers showing weak exchange effects: a synthetic, structural, spectroscopic and computation study
Three dimanganese(iii) complexes have been synthesised and fully characterised by standard spectroscopic methods and spectroelectrochemistry. Each MnIII ion is chelated by a salen type ligand (H2L), but there is variation in the bridging group: LMn(OOCCH[double bond, length as m-dash]CHCOO)MnL, LMn(OOCC6H4COO)MnL, and LMn(OOCC6H4C6H4COO)MnL. X-ray diffraction revealed an axial compression of each six-coordinate high-spin d4 MnIII ion, which is a Jahn-Teller-active ion. Temperature dependent magnetic susceptibility and variable temperature-variable field (VTVH) magnetisation measurements, as well as high-frequency and -field EPR (HFEPR) spectroscopy were used to accurately describe the magne…
A five-coordinate manganese(iii) complex of a salen type ligand with a positive axial anisotropy parameter D.
A new high-spin d4 roughly trigonal–bipyramidal (TBP) manganese(III) complex with a salen type ligand (H2L), namely MnL(NCS)·0.4H2O, has been synthesised and characterised by elemental analysis, ESI mass spectrometry, IR and UV-vis spectroscopy, and spectroelectrochemistry. X-ray diffraction analysis revealed an axial compression of the approximate TBP. Temperature dependent magnetic susceptibility and variable-temperature variable-field (VTVH) magnetisation measurements, as well as high-frequency and -field EPR (HFEPR) spectroscopy, were used to accurately describe the magnetic properties of this complex and, in particular, determine the spin Hamiltonian parameters: g-values and the zero-f…
Copper(II) complexes with 1,5-bis(2-hydroxybenzaldehyde)carbohydrazone
Abstract The acid–base properties of 1,5-bis(2-hydroxybenzaldehyde)carbohydrazone (H4L) and its thioanalogue 1,5-bis(2-hydroxybenzaldehyde)thiocarbohydrazone (H4LS) have been studied experimentally by pH-potentiometry and UV–Vis spectrophotometry and theoretically by using DFT methods. Copper(II) complexes [Cu2(HL)(DMSO)2(H2O)]NO3·H2O (1), [{Cu2(HL)(DMF)(H2O)}n][{Cu2(HL)(DMF)NO3}n](NO3)n (2), [Cu2(HL)(DMF)2(H2O)]HSO4·H2O (3), [Cu2(HL)(DMF)2(H2O)][Cu2(HL)(SO4)(H2O)(DMF)2]·2H2O (4) and [Cu4(HL)2(HSO4)(DMF)2]HSO4 (5), where H4L = 1,5-bis(2-hydroxybenzaldehyde)carbohydrazone, have been synthesised. Complexes 1–3 have been characterised by elemental analysis, IR spectroscopy, ESI mass spectromet…
