Abstract

In the title compound, {Nd(NO(3))(C(6)H(5)NO(2))(2)(H(2)O)(3)(2)·H(2)O}(n), the Nd(III) atom is nine-coordinated by four O atoms from four pyridinium-4-carboxyl-ate ligands, two O atoms from a chelating nitrate anion and three water mol-ecules in a distorted tricapped trigonal-prismatic coordination geometry. Adjacent Nd atoms are linked by the bidentate pyridinium-4-carboxyl-ate ligands into a chain running along the b axis. The chains are further connected by O-H⋯O and N-H⋯O hydrogen bonds into a three-dimensional network.

摘要

在标题化合物{Nd(NO₃)(C₆H₅NO₂)₂(H₂O)₃₂·H₂O}ₙ中，Nd(III)原子由四个吡啶-4-羧酸根配体的四个O原子、一个螯合硝酸根阴离子的两个O原子和三个水分子以扭曲的三帽三棱柱配位几何构型九配位。相邻的Nd原子通过双齿吡啶-4-羧酸根配体连接成沿b轴延伸的链。这些链通过O—H⋯O和N—H⋯O氢键进一步连接成三维网络。
