Strained metallocenophanes with late transition metals in the bridge: syntheses and structures of nickel- and platinum-bridged [1]ferrocenophanes.

Diamondoids and DNA Nanotechnologies

Diamondoids are cage-like saturated hydrocarbons consisting of fused cyclohexane rings. The Diamondoids family of compounds is one of the best candidates for molecular building blocks (MBBs) in nanotechnology to construct organic nanostructures compared to other MBBs known so far. The challenge is to find a route for self-assembly of these cage hydrocarbons and their applications in the bottom-...

Quantum Mechanic Studies of Natural Bond Orbital & Stabilities of [CuCH2SiMe3]4Complexes With Different Halogens

The asymmetric unit of the title compound,  Contains two independent molecules. The Cu atoms are four coordinated in distorted tetrahedral configuration by two atoms from 5,5`-dimethyl-2,2`- bipyridine and two terminal atoms. In the Cuystal structure, inter molecular hydrogen bonds link the molecules. The are  contacts between the methyl groups and the pyridine and five member rings containing ...
