Abstract

In the title compound, {(C(16)H(22)N(4))[Co(C(10)H(2)O(8))(H(2)O)(4)]·2H(2)O}(n), the octa-hedrally coordinated Co(II) atom is situated on an inversion center and possesses four aqua ligands. The Co atoms are linked into an anionic coordination polymer chain by bis-monodentate pyromellitate ligands. The chain motifs are connected into a supra-molecular layer by hydrogen bonding mediated by uncoordinated water mol-ecules. Charge balance is provided by doubly protonated bis-(4-pyridylmeth-yl)piperazine units, which are anchored to the coordination polymer chain motifs by N-H⋯O hydrogen bonding.

摘要

在标题化合物{(C₁₆H₂₂N₄)[Co(C₁₀H₂O₈)(H₂O)₄]·2H₂O}ₙ中，八面体配位的Co(II)原子位于一个反演中心上，并拥有四个水配体。Co原子通过双单齿均苯四甲酸根配体连接成阴离子配位聚合物链。链状结构单元通过未配位水分子介导的氢键连接成超分子层。电荷平衡由双质子化的双(4-吡啶甲基)哌嗪单元提供，这些单元通过N-H⋯O氢键锚定在配位聚合物链状结构单元上。
