The reactions of 2-amino-2-methyl-1-propanol (MepH) with Co(ClO₄) ₂•6H₂O in the presence of acetic acid gave [Co₂ (Mep) ₃ (OAc)(MepH)](ClO₄) ₂•MepH (1) and [CoIII ₄ CoII ₂ (Mep)8(μ₃-OH) ₂ (OAc) ₄](ClO₄) ₂• 2EtOH•2H₂O (2). They were characterized by elemental analysis, IR and single crystal X-ray diffraction analysis. Compound 1 presents a dinuclear structure with its two Co atoms linked by two Mep⁻ ligands and one acetate ligand. The two Co(II) and four Co(III) centers in 2 are held together by eight Mep⁻ ligands, two μ₃-OH⁻ ions and four acetate ligands to form a hexanuclear skeleton which contains a defected face-shared dicubane core. Their discrete polynuclear units are further linked into double-layered and mono-layered two-dimensional H-bonded framework, respectively.
