چکیده

The new flexible spacer ligand 1,3-bis(4-pyridyl)propane-N,N'-dioxide forms three classes of isomorphous compounds with metal(iI) thiocyanates at controlled ligand-metal molar ratios, and its mu3-O,O,O' mode leads to a pair of coordination networks having the same (4, 4) topological characteristics but different mono- and di-nuclear nodes.

Synthesis and characterization of mono- and heterodinuclear complexes of dinucleating macrocyclic ligand bearing hexa- and pentadentate coordination sites

Macrocyclic heterobinuclear Zn(II)–Cu(II) complexes with phenol based dicompartmental ligands possessing contiguous hexa- and penta-coordination sites were prepared by a stepwise procedure. The ligands include similar N4O2 and dissimilar N(imine)3O2 and N(amine)3O2 coordination sites sharing two phenolic oxygen atoms. The six-coordination site comprises two pyridyl pendant arms on the amine nit...

Plumbum(II) and Zinc(II) Complexes with 5-Chlorosalicylic Acid: Structure and Propertie

Abstract: Two new transition metal complexes, containing the acidic ligand 5-chlorosalicylic acid (H2L5), and 1,10-phenanthroline(phen) and 1,3-Di(4-pyridyl)propane (bpp) as secondary ligands are reported. They are formulated as {[Pb(HL5)2(phen)(H2O)]·H2O}n(1), [Zn2(HL5)4(bpp)2]n(2). All the complexes are characterized by single-crystal X-ray diffractions. Compoud 1 crystallizes in the triclini...
