Structure of rhodocene

Rhodocene is an organometallic 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. The [Rh(C₅H₅)₂] radical is found above 150 °C or when trapped by cooling to liquid nitrogen temperatures (−196 °C). At room temperature, pairs of these radicals join via their cyclopentadienyl rings to form a dimer, a yellow solid. 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 study metal–metal interactions in linked metallocenes which can potentially be used to make molecular electronics. Rhodocene can be synthesized by reacting rhodium chloride hydrate, cyclopentadiene, and ammonium hexafluorophosphate. (Full article...)

Today's featured picture

Anne Dallas Dudley (November 13, 1876 – September 13, 1955) was a prominent activist in the women's suffrage movement in the United States. In 1917, she became the third vice president of the National American Woman Suffrage Association, where she contributed significantly to advancing legislation on the issue of women's suffrage. In 1920, along with several others, she led the campaign in Tennessee to approve ratification of the Nineteenth Amendment to the US Constitution. As a result, Tennessee became the 36th and deciding state to ratify the amendment, thereby giving women the right to vote throughout the country.
