Abstract

Reaction of N,N′,N″-tris-(2S)-2-hydroxypropyl-1,4,7-triazacyclononane (H3L) with MnCl2 in neutral or slightly basic conditions affords (MnII(H3L)(L)MnIV][PF6]3, a mixed-valence, hydrogen-bridged dimer in which the MnIV half has pseudooctahedral geometry and the MnII half has trigonal prismatic geometry.
