An Ni-based coordination polymer with a bamboo-like crystal structure
An Ni-based coordination polymer, namely, poly[tetra-aqua-bis-[4,7-bis-(1<i>H</i>-pyrazol-4-yl)benzo[<i>c</i>][1,2,5]thia-diazole][μ<sub>4</sub>-5,5'-(1,3,6,8-tetra-oxo-1,3,6,8-tetra-hydro-benzo[<i>lmn</i>][3,8]phenanthroline-2,7-di-yl)diisophthalato]dinickel(II)], {[Ni<sub>2</sub>(C<sub>30</sub>H<sub>10</sub>N<sub>2</sub>O<sub>12</sub>)(C<sub>12</sub>H<sub>8</sub>N<sub>6</sub>S)<sub>2</sub>(H<sub>2</sub>O)<sub>4</sub>]·2C<sub>3</sub>H<sub>7</sub>NO·H<sub>2</sub>O} <sub><i>n</i></sub> or <b>Ni-BIBT-BINDI</b>, with a crystal structure reminiscent of bamboo has been synthesized, the Ni<sup>2+</sup> 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.
