Syntheses of low-valent nitrosyl complexes of rhenium and X-ray structure of trans-[ReCl(NO)(Ph 2PCH 2CH 2PPh 2) 2][NO 3] 2 with nitrosyl derived nitrates

Abstract

The nitrosyl complexes trans-[ReCl(NO)(dppe) 2]A 2 ( 1; A  BF 4 or NO 3; dppe  Ph 2PCH 2CH 2−PPh 2) and trans-[ReCl(NO)(dppe) 2][BF 4] ( 2) have been prepared from the reactions of NO[BF 4] or NO with trans-[ReCl(N 2)dppe) 2]. An unusual facile oxidation of NO to nitrate is involved in the formation of ( 1, A  NO 3), the X-ray structure of which is reported.
