dualphosphine
Dualphosphine is a hypothetical or theoretical organophosphorus compound with the general formula (RP)2. This formula implies a molecule containing two phosphorus atoms linked by a single bond, with each phosphorus atom also bonded to an organic group R. The existence and stability of such molecules are dependent on the nature of the organic substituent R. Simple alkyl or aryl groups might lead to highly reactive or unstable species due to steric hindrance or electronic repulsion between the phosphorus atoms.
The bonding within a potential dualphosphine molecule would involve a phosphorus-phosphorus single bond. The electronic configuration
