Rhodocene is a chemical compound with the formula Rh(C5H5)2. Each molecule contains an atom of rhodium bound between two planar systems of five carbon atoms known as cyclopentadienyl rings in a sandwich arrangement. It is an organometallic compound as it has covalent rhodium–carbon bonds. Biomedical researchers have examined the applications of rhodium compounds and their derivatives in medicine and reported one potential application for a rhodocene derivative as a radiopharmaceutical to treat small cancers. Rhodocene derivatives are also used to synthesise linked metallocenes so that metal–metal interactions can be studied; potential applications of these derivatives include molecular electronics and research into the mechanisms of catalysis. The value of rhodocenes tend to be in the insights they provide into the bonding and dynamics of novel chemical systems, rather than their direct use in applications.

___________________________ Wikiquote quote of the day:

I perceive the world in fragments. It is somewhat like being on a very fast train and getting glimpses of things in strange scales as you pass by. A person can be very, very tiny. And a billboard can make a person very large. You see the corner of a house or you see a bird fly by, and it's all fragmented. Somehow, in painting I try to make some logic out of the world that has been given to me in chaos. I have a very pretentious idea that I want to make life, I want to make sense out of it. The fact that I am doomed to failure — that doesn't deter me in the least. --Grace Hartigan http://en.wikiquote.org/wiki/Grace_Hartigan
