Abstract: In this research, we represented the structural characterization and preparation of two La(III)-based coordination polymers {[La(TATAB)(H2O)](H2O)2}n (1, H3TATAB\u2009=\u20094,4,4‚Ä?s-triazine-1,3,5-triyltri-m-aminobenzoic acid) and {[La(TCA)(H2O)](H2O)4}n (2, H3TCA\u2009=\u20091,3,5-tris (4-carbonylphenyloxy) benzene) by the usage of two flexible tricarboxylate ligand with different donor sites as the joints along with the different functional backbones. Furthermore, the nanostructures of complexes 1 and 2 (denoted as nano 1 and nano 2 hereafter) have been prepared via a sonochemical synthesis approach. The results indicated that nano 1 can block the SCC-25 cancer cells‚Ä?proliferation. Moreover, Annexin V-FITC/PI assay was carried out to discover the SCC-25 (Phosphorus cancer cells of human tongue) cancer cells‚Ä?apoptosis after compounds treatment. The data showed that nano 1 significantly improve the apoptotic cells numbers rather than nano 2. In addition, nano 1 facilitated the ROS‚Äôs (ROS\u2009=\u2009reactive oxygen species) accumulation which are important in cell apoptosis. The western blot showed that nano 1 induce cell apoptosis via up-regulating FHIT expression.

 This is one of a large number of coordination-chemistry papers that appear to have all been written according to a template. - All draw on the same small pool of papers to illustrate the broad range of applications and properties of MOFs. Even when the in-text citations match the references, one might expect independent authors to think of different examples. - Many cite Zhao, Kang and Yao (2019) -- **Research and Application of Acoustic Emission Signal Processing Technology** -- which is completely irrelevant to the topic, but became part of the template anyway. - The vast majority of email identities for corresponding authors were formed by taking an underscore-separated name and appending 666 or 66 . I am advised that these are auspicious numbers with positive associations. So one possibility is that the authors all decided independently to generate email accounts with this format. The alternative is that *some outside contractor* handled the task of negotiating with journals (generating these disposable accounts in the process) - perhaps also the task of writing the manuscripts, using a single Bibliography file to save time. For a (partial) list [see here] In the following, (some of) the recurring References are labelled 1 to 14 .
