3,5-Lutidine pentaaqua sulfate complexes of first-row transition metals: [M(3,5-lutidine)(H2O)5]SO4, with M = Mn, Co, Ni, and Zn

The reactions of MnSO4·H2O, CoSO4·7H2O, NiSO4·6H2O and ZnSO4·7H2O with 3,5-lutidine (3,5-dimethylpyridine) yield crystals of pentaaqua(3,5-dimethylpyridine-κN)manganese(II) sulfate, [Mn(C7H9N)(H2O)5]SO4, (1), pentaaqua(3,5-dimethylpyridine-κN)cobalt(II) sulfate, [Co(C7H9N)(H2O)5]SO4, (2), pentaaqua(...

Description
Summary:The reactions of MnSO4·H2O, CoSO4·7H2O, NiSO4·6H2O and ZnSO4·7H2O with 3,5-lutidine (3,5-dimethylpyridine) yield crystals of pentaaqua(3,5-dimethylpyridine-κN)manganese(II) sulfate, [Mn(C7H9N)(H2O)5]SO4, (1), pentaaqua(3,5-dimethylpyridine-κN)cobalt(II) sulfate, [Co(C7H9N)(H2O)5]SO4, (2), pentaaqua(3,5-dimethylpyridine-κN)nickel(II) sulfate, [Ni(C7H9N)(H2O)5]SO4, (3), and pentaaqua(3,5-dimethylpyridine-κN)zinc(II) sulfate, [Zn(C7H9N)(H2O)5]SO4, (4), which were characterized by single-crystal X-ray diffraction. The four crystals are isostructural, demonstrating near identical unit-cell parameters and atomic positions. The metal atoms are all octahedrally coordinated, with one lutidine ligand and five water ligands. The sulfate dianion hydrogen bonds with the coordinated water molecules of the dicationic metal complex salts, generating infinite three-dimensional networks.
