Every phosphorus atom has a lone pair of electrons, facilitating coordination of Lewis acids, particularly metal atoms and ions. 2. Phosphorus tends to feature smaller bond angles compared to carbon [4] which results in a different

Webtate ligands. Here, regardless of the ring size, the oligophos-phinesalways stabilize the metal center in a1,3-coordination mode.However,the highest diversity of coordination modesis found for phosphorus ligandsthat do not bear any organic substituents.[1] These so called P n ligandsare usuallyobtained Web01. jul 1997. · They suggested that the change is due to association of poly- or oligophos- phates with core subunits (Kusano,S. and Ishihama,A., in preparation). The altered stationary phase forms of RNAP manifested different promoter recognition properties from the exponential phase RNAP.
