Complexes of gold, silver and copper with Z,Z-PPh₂CH₂CBu^t= N–N=C(Bu^t)CH₂PPh₂ containing a nine-membered chelate ring: crystal structure of [AuCl{Z,Z-PPh₂CH₂CBu^t =N–N=C(Bu^t) CH₂PPh₂}]

Abstract

Complexes of gold, silver and copper with the azine diphosphine Z,Z-PPh₂CH₂CBu^t =N–N=C(Bu^t)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-PPh₂CH₂CBu^t =N–N=C(Bu^t)CH₂PPh₂ }] was determined.
