Aggregation of [Ln(12)(III)] clusters by the dianion of 3-formylsalicylic acid. Synthesis, crystal structures, magnetic and luminescence properties

2019

Three isostrucutral dodecanuclear clusters with the general formula [Ln(12)(fsa)(12)(mu f(3)-OH)(12)(DMF)(12)]center dot nDMF (fsa(2-) is the dianion of 3-formylsalicylic acid; Ln = Eu 1, Gd 2, Dy 3) have been obtained from the reaction of fromylsalicyclic acid (H(2)fsa), tetrabutylammonium hydroxide and Ln(NO3)(3)center dot 6H(2)O in methanol/DMF. Their structure consists of four vertex-sharing heterocubanes. Each heterocubane unit is assembled from four Ln(III) ions, three mu(3)-OH groups and one mu(3)-oxygen atom arising from the fsa(2-) carboxylato group. The photophysical properties of the europium derivative investigated at both 300 and 80 K sustain a relative intense emission obtaine…

Copper(II) complexes with 1,5-bis(2-hydroxybenzaldehyde)carbohydrazone

2014

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…
