Received: 16 January 2012; in revised form: 21 February 2012 / Accepted: 28 February 2012 / Published: 2 March 2012 Abstract: The facile preparation of a racemic hydrazine bridged diphosphonium compound possessing a ring system analogous to bicyclo[3.3.2]decane is reported. Although the reaction yield is low, the structure of the compound, which possesses an eight-membered ring, two phosphonium cationic centers, a biimino bridge, mo
