Polynuclear transition metal complexes. The reactivity of the new potentially binucleating ligand 2, 6-diacetylpyridine-bis(1′-phthalazinylhydrazone) towards NiII, CuII and ZnII salts, and crystal and molecular structure of {bis[2,6-diacetylpyridine-bis(1′-phthalazinylhydrazonato)nickel(II)]} dimethylformamide and water solvate

Crystallisation Solvent Influence on the Crystal Structures of MnII and NiII Complexes with 2,6-bis(1-salicyloylhydrazonoethyl)pyridine, H4daps

“…This does not occur in complex 5, leading to a less symmetrical compound. However all the bond distances and angles are comparable between the complexes and are in the range of those expected for Ni complexes with hydrazone ligands [16,21,23].…”

Electrochemical Synthesis and X-ray Characterisation of Cadmium Complexes Containing 2,6-Bis(1-salicyloylhydrazonoethyl)pyridine − the Influence of the Supporting Electrolyte on the Nature of the Isolated Compounds

“…To verify this, the aforementioned electrochemical reaction was performed in the presence of other electrolytes, such as NH 4 PF 6 , N(CH 3 ) 4 Br, or N(CH 2 CH 2 CH 2 CH 3 ) 4 Br. In the case of NH 4 PF 6 , the reaction yielded 1, as one would expect in view of the poor nucleophilicity of PF 6 Ϫ . The use of the bromide electrolytes led to transparent yellow acetonitrile solutions, rather than to the insoluble complex 1.…”

Synthesis and characterization of a binuclear copper(II) complex [Cu(H2slox)]2 from polyfunctional disalicylaldehyde oxaloyldihydrazone and its heterobinuclear copper(II) and molybdenum(VI) complexes

“…A survey of literature reveals that although work on metal complexes of monohydrazide-based ligands and their Schiff bases has been carried out in some detail [18][19][20][21], those on metal complexes of dihydrazones are quite meager [16,17,[22][23][24][25][26][27]. It further reveals that work on heterobimetallic complexes of dihydrazones is virtually absent [26,27].…”
