Bfg. Johnson et al., THE PREPARATION AND CHARACTERIZATION OF THE MIXED-VALENCE COMPLEX DIANION [MN3(CO)6(MU-2-NO2)4(MU-2-ONO)2]2-, Journal of the Chemical Society, Chemical Communications, (17), 1993, pp. 1345-1346
Treatment of Mn(CO)5Cl with trimethylamine N-oxide in CH2Cl2 in the pr
esence of [PPN]NO2 [PPN+ = (Ph3P)2N+] yields the new dianion [Mn3(CO)6
(mu2-NO2)4(mu2-ONO)2]2-, which has been shown to contain a trinuclear
Mn3 mixed valence unit linked by both nitro- and nitrito-bridges.
