An Ni-based coordination polymer, namely, poly[tetra-aqua-bis-[4,7-bis-(1-pyrazol-4-yl)benzo[][1,2,5]thia-diazole][μ-5,5'-(1,3,6,8-tetra-oxo-1,3,6,8-tetra-hydro-benzo[][3,8]phenanthroline-2,7-di-yl)diisophthalato]dinickel(II)], {[Ni(CHNO)(CHNS)(HO)]·2CHNO·HO} or , with a crystal structure reminiscent of bamboo has been synthesized, the Ni ions exhibiting a slightly distorted octa-hedral coordination geometry with N atoms and O atoms. The bond lengths of the Ni-O bonds range from 2.032 to 2.121 Å, and those of the Ni-N bonds are approximately 2.080 Å. The BINDI ligands are connected to each other by the Ni-O bonds, which form the backbone of the bamboo, while the BIBT ligands are connected to the backbone of the bamboo through Ni-N bonds and grows on both sides of the bamboo, constituting the bamboo leaves.
一种镍基配位聚合物，即聚[四水合双-[4,7-双-(1-吡唑-4-基)苯并[][1,2,5]噻二唑][μ-5,5'-(1,3,6,8-四氧代-1,3,6,8-四氢苯并[][3,8]菲咯啉-2,7-二亚基)二间苯二甲酸根]二镍(II)]，{[Ni(C₁₀H₆N₄O)(C₈H₄N₂S₂)(H₂O)₄]·2C₃H₇NO·H₂O} 或 ，其晶体结构让人联想到竹子，已被合成出来，镍离子与氮原子和氧原子呈现出略微扭曲的八面体配位几何构型。镍-氧键的键长范围为2.032至2.121 Å，镍-氮键的键长约为2.080 Å。BINDI配体通过镍-氧键相互连接，形成竹子的主干，而BIBT配体通过镍-氮键连接到竹子的主干上，并在竹子两侧生长，构成竹叶。
