Formation of a ligand-based mixed-valence cluster triggered by dehydration condensation of semiquinonates with o-phenylenediamines
A tetrameric [Co-II(phenSQ)(2)](4) with homovalent semiquinonates reacts with o-phenylenediamines to give a ligand-based mixed-valence pentanuclear cluster [{Co-5(II)(phenSQ)(4)(phen-Cat)(3)(THF)(3)(H2O)}center dot THF], containing two differently charged ligands, whose formation is triggered by a dehydration condensation reaction between the semiquinonates and o-phenylenediamines.
