In modern coordination chemistry, supramolecular coordination complexes take advantage of ligand design to control the shapes and sizes of such architectures. Here we describe how to utilize starting building blocks and a multifunctional ligand to rationallydesign and synthesize different types of discrete assemblies. Using a hydroxamate ligand featuring two pair of chelating sites together with half-sandwich

4′″-quaterpyridyl ligand, with d6 ReI and d8 PdII and PtII metal centres has been investigated. This has lead to the synthesis, isolation and characterisation of seven newcomplexes. The UV–Vis absorption spectra of the newcomplexes are dominated by intraligand and charge transfer bands. While the d8 metal complexes are not emissive, the ReI complexes display broad unstructured luminescence that is

The synthesis and properties of palladium(II) and platinum(II) complexes with quadridentateSchiffbases derived from the condensation of salicylaldehyde and (R)-1,2-diamines are described. The ligand conformation of the platinum(II) complexes is discussed on the basis of the circular dichroism and the 1H n.m.r. spectra. The anomalous patterns of the circular dichroism spectra of palladium(II) derivatives

Opposite influence of calf thymus DNA on the rate of substitution of ethylenediamine, by thiourea, in the complex cations [Pd(bpy)(en)]2+ and [Pd(bromazepam)(en)]2+ (bromazepam = 7-bromo-1,3-dihydro-5-(2-pyridyl)-2H-1,4-benzodiazepin-2-one)

Calf thymus DNA inhibits the substitution of ethylenediamine, by thiourea, in [Pd(bpy)(en)]2+ and catalyses the same reaction in [Pd(bromazepam)(en)]2+ (bromazepam = 7-bromo-1,3-dihydro-5-(2-pyridyl)-2H-1,4-benzodiazepin-2-one); this kinetic effect can be related to the different binding modes of the two complexes to the biopolymer.
