Abstract

In the title compound, Zn(C(18)H(14)N(4))(2)(H(2)O)(4)(2)·1.49H(2)O, the Zn(II) atom, lying on an inversion center, is coordinated by two N atoms from two N,N'-bis-(pyridin-3-yl-methyl-idene)benzene-1,4-diamine ligands and four water mol-ecules in a distorted octa-hedral geometry. The nitrate anion is disordered over two sets of sites, with an occupancy ratio of 0.744 (4):0.256 (4). The uncoordinated water mol-ecule is also disordered with an occupancy factor of 0.744 (4). O-H⋯O and O-H⋯N hydrogen bonds link the complex cations, nitrate anions and uncoordinated water mol-ecules into a supra-molecular layer parallel to (102).

摘要

在标题化合物Zn(C₁₈H₁₄N₄)₂(H₂O)₄₂·1.49H₂O中，位于对称中心的Zn(II)原子由两个N,N'-双-(吡啶-3-基-亚甲基)苯-1,4-二胺配体的两个N原子和四个水分子以扭曲的八面体几何构型配位。硝酸根阴离子在两组位置上无序，占有率为0.744 (4):0.256 (4)。未配位的水分子也无序，占有率因子为0.744 (4)。O—H⋯O和O—H⋯N氢键将络合阳离子、硝酸根阴离子和未配位的水分子连接成平行于(102)的超分子层。
