Black (*) phosphorus is composed of interpenetrating rings of this many phosphorous atoms.
Complexes with this number of methide ligands bonded to some second row transition metals have an unusual geometry with bond angles of 95 and 85 degrees. Two Science papers in 2011 and 2012 by the DeBeer lab and coworkers, and the Einsle and Rees labs, respectively, established that the central atom in theFeMoco cofactor was a carbon of this valency. The coordination complex hexacyanoferrate(II) has this many d electrons. Black (*) phosphorus is composed of interpenetrating rings of this many phosphorous atoms. Although rings with this many carbon atoms are not the kinetically most favorable, they are usually the thermodynamically most stable. Under ideally basic conditions, the chelator EDTA binds this many times to its metal center. A wellÂ­known molecule with this many carbon atoms has chair and boat conformations. For 10 points, name this number of carbon atoms in the molecule benzene.
