The laboratory preparation of 20-methylcholanthrene from desoxycholic acid by Wieland and Dane (20) in 1933 encouraged speculation concerning the role that polynuclear aromatic hydrocarbons might play as endogenous carcinogenic agents, but in the succeeding decade progress in the characterization of endogenous chemical carcinogens has been extremely slow. Several investigators have attempted to...

The chemistry of polynuclear gold(I) complexes has attracted increasing attention in the past few decades. With a closedshell electronic configuration of d, gold(I) ions adopt a linear two-coordinate coordination geometry and tend to form weak metal⋯metal interactions, which were termed “aurophilic interactions” by Schmidbaur. They are found in a huge number of polynuclear aggregates that posse...

Abstract Photocatalytic water splitting and carbon dioxide photoreduction are considered effective strategies for alleviating the energy crisis environmental pollution. Polynuclear metal-oxo clusters possess excellent electron storage/release ability unique catalytic properties via intermetallic synergy, which enables them with great potential in environmentally friendly photosynthesis. Importa...

We describe a 1.2 A X-ray structure of a double-stranded B-DNA dodecamer (the Dickerson Dodecamer, DDD, [d(CGCGAATTCGCG)]2) associated with a cytotoxic platinum(II) complex, [{trans-Pt(NH3)2(NH2(CH2)6(NH3+)}2-mu-{trans-Pt(NH3)2(NH2(CH2)6NH2)2}] (TriplatinNC). TriplatinNC is a multifunctional DNA ligand, with three cationic Pt(II) centers, and directional hydrogen bonding functionalities, linked...

The formation of cobalt nanoclusters from polynuclear Co-alkyne species can be directed by multivalent calixarene ligands; thermochemical studies of Con-calixarenes reveal the influence of multivalency in prenucleation and postnuclear growth processes.

An unprecedented polynuclear metal cluster-pillared triangular prism was built by a macrocycle-directing strategy. Discrete architectures of three silver cluster-involved metallosupramolecules were characterized by single crystal X-ray crystallography and spectroscopy studies.
