Open coordination sites-induced structural diversity of a new series of Cu(II) complexes with tridentate aroylhydrazone Schiff base

Synthesis, crystal structure and cytotoxicity assays of a copper(II) nitrate complex with a tridentate ONO acylhydrazone ligand. Spectroscopic and theoretical studies of the complex and its ligand

“…The H 2 L ligand crystallizes as E isomer in the tautomeric amido form (I) (Scheme 3), where the hydrazides fragment adopts the keto-amine arrangement [23]. The C8=N1, C9=O2 and the C9-N2 bond lengths are in close agreement with the formally double and single bond character [37] and also with the reported values for some hydrazones in the amido tautomeric form (I) [38][39][40][41]. The solid state structure of the copper compound, [Cu(HL)(OH 2 ) 2 ](NO 3 ), was determined by Xray diffraction methods.…”

One-dimensional magnetism in a facile spin 1/2 Heisenberg antiferromagnet with a low saturation field

“…1–3 Such MOCPs can vary from simple one-dimensional chains with small ligands to large mesoporous frameworks like metal–organic frameworks. 4,5 These materials find very diverse potential applications including magnetism, 6–9 optics, 10–12 sensors, 13,14 medical diagnostics, 15,16 energy storage and batteries, 17 data storage, 18,19 etc. Of the many applications mentioned above, MOCPs have a very important application as molecular magnets 20,21 in the area of low dimensional magnetism from both a fundamental and an applied point of view, where they are now being researched as potential candidates for quantum computers.…”
