Abstract

In the polymeric title complex, {[Ni(C(2)H(5)NO(2))(2)(H(2)O)(2)]Cl(2)}(n), the Ni(II) atom lies on an inversion center and is in a distorted octa-hedral NiO(6) configuration, with four carboxyl-ate O atoms from four zwitterionic glycine mol-ecules forming the equatorial plane and two water O atoms occupying the axial positions. The Cl(-) counterions lie in the inter-stices. The Ni(II) complexes are linked into polymeric sheets parallel to the bc plane. These sheets are then further connected into a three-dimensional network by O-H⋯O, O-H⋯Cl and N-H⋯Cl hydrogen bonds, together with weak C-H⋯O inter-actions.

摘要

在聚合标题配合物{[Ni(C₂H₅NO₂)₂(H₂O)₂]Cl₂}ₙ中，Ni(II)原子位于一个对称中心上，处于扭曲的八面体NiO₆构型，来自四个两性离子甘氨酸分子的四个羧酸根O原子形成赤道平面，两个水分子O原子占据轴向位置。Cl⁻抗衡离子位于空隙中。Ni(II)配合物连接成平行于bc平面的聚合物片层。然后这些片层通过O—H⋯O、O—H⋯Cl和N—H⋯Cl氢键以及弱的C—H⋯O相互作用进一步连接成三维网络。
