Homoligand and mixed ligand barium diketonate complexes have been synthesized and characterized by X-ray structure determination. Homoligand complexes with dipivaloylmethane hexafluoroacetone and pivaloyltrifIuoroacetone have oligigomeric or polymeric structure. The mixed complexes with additional anionic ligands (ClOH-, Piv-) form pentanuclear complexes. The structures of the mixed ligand comp...

The dinuclear dialkoxo-bridged complexes [(TiCl)(2)(mu-O(2)L)(mu-{(eta(5)-C(5)Me(4)SiMeO)(2)(mu-O)})] (O(2)L = 1,2-O(2)C(2)H(4), 1,2-O(2)C(6)H(4), 1,2-(OCH(2))(2)C(6)H(4), O(2)SiPh(2)) were obtained by reaction of [(TiCl(2))(2)(mu-{(eta(5)-C(5)Me(4)SiMeO)(2)(mu-O)})] () with the corresponding dilithium salt () or diol (, , ). Alkylation of and with ClRMg afforded [(TiR)(2)(mu-O(2)L)(mu-{(eta(5)...

Heterodinuclear complexes, syn-[MPt(μ-pyt)2(bpy)2](n+) (syn-[MPt], M = Pd(2+), Au(3+), Hpyt = pyridine-2-thiol, bpy = 2,2'-bipyridine), were synthesized as a selective geometrical isomer by stepwise complexation. X-ray analyses of the hexafluorophosphate salts of these complexes proved their dinuclear structures with short M···Pt distances (2.9084(4) Å for syn-[PdPt] and 2.9071(4) Å for syn-[Au...

A series of ligands containing a 1,4-disubstituted 1,2,3-triazole unit have been used for the formation triple-stranded dinuclear Ru(II) complexes. In contrast to previously reported complexes labile metals, use inert enabled stereoisomeric mixtures diruthenium(II) be accessed. The chromatographic resolution enantiomers helicate more rigid 1,4-xylyl spacer was carried out on cellulose. ligand m...

Hybrid complexes with N,N'-bis(2-benzimidazolylmethyl)amine and cyclen moieties are novel enzyme mimics and controlled DNA release materials, which could interact with DNA through three models under different conditions. In this paper, the interactions between plasmid DNA and seven different complexes were investigated, and the methods to change the interaction patterns by graphene oxide (GO) o...

Two dinuclear [Ni2L2(o-(NO2)C6H4COO)2(H2O)] (1), [Ni2L2(p-(NO2)C6H4COO)2(H2O)]·0.5CH3OH (2) complexes and one trinuclear [Ni3L2(p-(NO2)C6H4COO)4]·C2H5OH (3) Ni(II) complex have been synthesized using a tridentate Schiff base ligand, 1-[(3-dimethylamino-propylimino)-methyl]-naphthalen-2-ol (HL) along with ortho- and para-nitro benzoate as co-ligands. All these three (1-3) complexes have been cha...
