The reactions of MnSO·HO, CoSO·7HO, NiSO·6HO and ZnSO·7HO with 3,5-lutidine (3,5-di-methyl-pyridine) yield crystals of penta-aqua-(3,5-di-methyl-pyridine-κ)manganese(II) sulfate, [Mn(CHN)(HO)]SO, (), penta-aqua-(3,5-di-methyl-pyridine-κ)cobalt(II) sulfate, [Co(CHN)(HO)]SO, (), penta-aqua-(3,5-di-methyl-pyridine-κ)nickel(II) sulfate, [Ni(CHN)(HO)]SO, (), and penta-aqua-(3,5-di-methyl-pyridine-κ)zinc(II) sulfate, [Zn(CHN)(HO)]SO, (), 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 octa-hedrally coordinated, with one lutidine ligand and five water ligands. The sulfate dianion hydrogen bonds with the coordinated water mol-ecules of the dicationic metal complex salts, generating infinite three-dimensional networks.
硫酸锰一水合物（MnSO₄·H₂O）、硫酸钴七水合物（CoSO₄·7H₂O）、硫酸镍六水合物（NiSO₄·6H₂O）和硫酸锌七水合物（ZnSO₄·7H₂O）与3,5-二甲基吡啶反应生成五水合（3,5-二甲基吡啶-κ）硫酸锰（II）晶体[Mn(C₇H₉N)(H₂O)₅]SO₄（I）、五水合（3,5-二甲基吡啶-κ）硫酸钴（II）晶体[Co(C₇H₉N)(H₂O)₅]SO₄（II）、五水合（3,5-二甲基吡啶-κ）硫酸镍（II）晶体[Ni(C₇H₉N)(H₂O)₅]SO₄（III）和五水合（3,5-二甲基吡啶-κ）硫酸锌（II）晶体[Zn(C₇H₉N)(H₂O)₅]SO₄（IV），这些晶体通过单晶X射线衍射进行了表征。这四种晶体结构相同，展示出几乎相同的晶胞参数和原子位置。金属原子均为八面体配位，有一个二甲基吡啶配体和五个水分子配体。硫酸根阴离子与二价金属络合物盐的配位水分子形成氢键，生成无限的三维网络结构。
