Complexes of gold, silver and copper with Z,Z-PPh2CH2CBut = N-N = C(But)CH2PPh2 containing a nine-membered chelate ring: crystal structure of [AuCl{Z,Z-PPh2CH2CBut = N-N = C(But)CH2PPh2}]

Abstract

Complexes of gold,silver and copper with the azine diphosphine Z,Z-PPh2CH2CBut=N-N=C(But)CH2PPh2 have been prepared and shown to contain the diphosphine in an unusual nine-membered chelate ring; the crystal structure of the chlorogold derivative [AuCl{Z,Z-PPh2CH2CBut=N-N=C(But)CH2PPh2}]was determined.
