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.
