The single-crystal X-ray structures of the hexacoordinate Co(II), Ni(II), and Mn(II) complexes of thiophene-2-carboxamide are reported as the perchlorate salts. The Co(II) and Ni(II) complexes are isostructural and crystallize in a cubic habit which is not frequently observed for complexes of metal ions with organic ligands (Pa $$\overline 3$$ , Z = 4, Co complex, 2, a = 16.466(2) Å, Ni complex, 3, a = 16.430(2) Å). The Mn(II) complex, 4, is monoclinic and contains four t-butanol molecules in the unit cell (P2/n, Z = 2, a = 9.7796(4) Å, b = 11.4847(4) Å, c = 23.3062(9) Å, β = 93.504(1)°). Hydrogen-bonding is a significant factor in all of these substances, especially for the Mn(II) complex. The structures and the infrared spectra of the compounds are discussed.
