The synthesis and full characterization of new half-sandwich ruthenium(II) complexes containing κ(3)(N,N,N)-hydridotris(pyrazolyl)borate (κ(3)(N,N,N)-Tp) and the water-soluble phosphanes 1,3,5-triaza-7-phosphatricyclo[3.3.1.1(3,7)]decane (PTA) and 1-methyl-3,5-diaza-1-azonia-7-phosphatricyclo[3.3....

We found that the gold-chlorine bond is significantly stronger in the case of the complex containing five-membered metallacyclic rings....

Three different tetraazamacrocyclic ligands containing four amide substituents that feature groups (namely allyl, styryl and propargyl groups) suitable for polymerisation have been synthesised. Gadolinium(III) complexes of these three ligands have been prepared as potential monomers for the synthesi...

These results should provide a means to control the magnetic coupling of the polynuclear Mn systems, which is instructive for the design of new molecular magnetic materials....

The first examples of platinum(II) complexes of 3-(aminomethyl)naphthoquinone Mannich bases have been synthesised and their crystal structures are described. Neutral and charged complexes have been obtained, fully characterised and their cytotoxic activities have also been investigated. 3-[(R(1)-ami...

This communication explores the effect of varying substituent bulk at the N9 position of the adenine moiety and its effect in dictating the structural aspects of silver-adenine frameworks. While adenine alone or 9-benzyl substituted ligand afforded mono and dinuclear dimeric entities, n-propyl subst...

The phthalodinitrile derivative 3 was prepared by the reaction of 1,4-dithioerythritol 1 and 4-nitrophthalonitrile 2 in dry DMF as the solvent in the presence of K(2)CO(3) as the base by the method of nucleophilic substitution of an activated nitro group in an aromatic ring. The template reaction of...

Ru(ii) complexes that bring together the properties of the dppz (dipyrido[3,2-a:2',3'-c]phenazine) intercalating residue and the properties of metal-coordinating macrocycles (L = 4,4'-(2,5,8,11,14-pentaaza[15])-2,2'-bipyridilophane) have been synthesised and their protonation and affinity for copper...

Four metal(ii)-N(1),N(3)-di(pyridin-4-yl)isophthalamide (L) complexes formulated as [Cu(L)(2)Cl(2)]·5.5H(2)O (1), [Ni(L)(2)Cl(2)]·5.5H(2)O (2), [Co(L)(m-BDC)]·DMF (3) (m-BDC = 1, 3-benzenedicarboxylic dianion) and [Cd(2)(L)(2)(m-BDC)(2)]·DMF·0.2H(2)O (4) have been solvothermally synthesized and...

The aminoglycosidic antibiotic hygromycin B presents a peculiar chemical structure, characterized by two sugar rings joined via a spiro connection. The Cu(ii) complex of hygromycin B in water solution was characterized by (1)H-NMR, UV-Vis, EPR and CD spectroscopy, combined with potentiometric measur...
