Abstract

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.

摘要

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。
