The reactions of 2-amino-2-methyl-1-propanol (MepH) with Co(ClO<sub>4sub>)<sub>2sub>⋅6H<sub>2sub>O in the presence of acetic acid gave [Co<sub>2sub>(Mep)<sub>3sub>(OAc)(MepH)](ClO<sub>4sub>)<sub>2sub>⋅MepH (1) and [Co\(^{\text {III}}_{4}\)Co\(^{\text {II}}_{2}\)(Mep)<sub>8sub>(μ<sub>3sub>-OH)<sub>2sub>(OAc)<sub>4sub>](ClO<sub>4sub>)<sub>2sub>⋅ 2EtOH ⋅2H<sub>2sub>O (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−sup> ligands and one acetate ligand. The two Co(II) and four Co(III) centers in 2 are held together by eight Mep−sup> ligands, two μ<sub>3sub>-OH−sup> 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.
