Abstract: The structure of the [Mn(HPClNOL)(eta(1)-NO3)(eta(2)-NO3)1 complex [HPClNOL = 1-(bis-pyridin-2-ylmethyl-amino)-3-chloropropan-2-ol] in the solid-state and in H2O/MeOH solution was investigated by monocrystal X-ray diffraction and ESI(+)-MS/MS. X-ray reveals that I is a seven-coordinated complex with a discrete mononuclear structure in which the manganese(II) ion is coordinated by the tripodal HPClNOL ligand and two nitrate ions, one monodentate and the other bidentate. ESI(+)-MS/MS shows that mononuclear, dinuclear and trinuclear manganese cationic species are present in solution, probably in equilibrium with neutral 1. This contrasting scenario illustrates for 1 the importance of both solid-state and in-solution characterizations of coordination compounds with potential bioinorganic interest. (c) 2007 Elsevier B.
