Abstract

In the title compound, {[CdCl(2)(C(16)H(20)N(4))(2)]·4H(2)O}(n), octa-hedrally coordinated Cd(II) ions, situated on crystallographic inversion centres, bearing trans-disposed chloride ligands, are linked into (4,4)-grid coordination polymer layers by tethering 1,4-bis-(3-pyridylmeth-yl)piperazine ligands. The layers are aligned parallel to the (01) crystal planes and aggregate by means of O-H⋯N, O-H⋯O and O-H⋯Cl hydrogen-bonding mechanisms imparted by cyclic water mol-ecule tetra-mers.

摘要

在标题化合物{[CdCl₂(C₁₆H₂₀N₄)₂]·4H₂O}ₙ中，位于晶体学反演中心的八面体配位Cd(II)离子带有反式排列的氯配体，通过连接1,4-双(3-吡啶甲基)哌嗪配体连接成(4,4)网格状配位聚合物层。这些层平行于(01)晶面排列，并通过环状水分子四聚体产生的O-H⋯N、O-H⋯O和O-H⋯Cl氢键作用机制聚集在一起。
