The reactions of OsO4 with derivatives or model systems (L) for the side chains of tissue proteins have been studied, alone and in the presence of unsaturated lipids (R). The following new complexes have been isolated and their structures studied by vibrational and 1H n.m.r. spectroscopy: Os2O6L4(L =α-N-benzoyl-L-histidine isobutyl ester, imidazole, 1-methylimidazole, 5,6-dimethylbenzimidazole, n-butylamine
