mu-1,2,4,5-tetrazine-N-1 : N-4-bis(pentaammineruthenium) tetracation: Synthesis and X-ray structure

摘要

The 2:1 reaction of [Ru(H2O)(2)(NH3)(5)](2+) with 1,2,4,5-tetrazine (tz) gives rise to the formation of the dinuclear complex ion [{Ru(NH3)(5)}(2)(mu-tz-N-1:N-4)](4+). Its tetraphenylborate and hexafluoro-phosphate salts have been fully characterized; the X-ray structure of the former has also been determined. (C) 2007 Elsevier B.V. All rights reserved.
