thiophene-3-acetate, 2mpa -2-methylpropanal), were synthesised using a self-assembly method. The obtained polymers were characterised using SC-XRD, FTIR, UV-Vis DRS, thermogravimetric and luminescence analyses. The polymer fluorescence studies showed that calcium complexes can emit light of different colours ranging from violet (1) and blue (2) to green (3). The molecular structure of each polymer consists of a calcium ion at the centre of a dodecahedral coordination sphere. The crystal structure consists of one dimensional zigzag chains that form a three-dimensional network via πAdditionally, a comparative structural analysis of CaCPs with lead(II) coordination polymers containing analogous linkers was performed as part of modelling studies to explore the substitution of calcium ions by lead ions in biological polymers.

“…It is a great challenge to obtain proper functional materials because the properties of coordination compounds depend on the type of both metal ions and connecting ligands. Our interest in this field concerns the chemistry of lead(II) [ 10 , 11 , 12 , 13 , 14 ] and bismuth(III) coordination polymers with heteroaromatic carboxylate ligands. When selecting a central ion, we focused on the multiple applications of Bi(III) compounds as, for example, photoluminescent materials [ 15 , 16 , 17 ], catalysts [ 18 ], medical drugs for gastrointestinal disorders caused by Helicobacter pylori or anticancer agents [ 19 , 20 , 21 , 22 ].…”

“…Considering all of the above aspects of interesting bismuth chemistry, herein, we present the synthesis and characterization of new Bi(III) metal-organic coordination polymers. Taking into consideration our previous experience in the construction of CPs based on Pb(II) ions [ 10 , 11 , 12 , 13 , 14 ], we paid special attention to the choice of a proper organic linker. We selected pyridine-2,3-dicarboxylic acid as the prolinker for this purpose.…”

Two novel coordination polymers, [Bi2(2,3pydc)2(2,3pydcH)2(H2O)]n (1) and {(Et3NH)2[Bi(2,3pydc)(2,3pydcH)Cl2]}n (2) were prepared using as a prolinker pyridine-2,3-dicarboxylic acid (2,3pydcH2). The obtained complexes were fully characterized by elemental analysis, TG/DTG, FT-IR, solid-state photoluminescence, DFT calculations and single-crystal X-ray diffraction. The obtained complexes crystallized in the triclinic P-1 space group (1) and comprise dimeric units with two crystallographically different Bi(III) centers (polyhedra: distorted pentagonal bipyramid and bicapped trigonal prism) and monoclinic P21/c space group (2) with a distorted monocapped pentagonal bipyramid of Bi(III) center. The various coordination modes of bridging carboxylate ligands are responsible for the formation of 1D chains with 4,5C10 (1) and 2C1 (2) topology. The photoluminescence quantum yield for polymer 2 is 8.36%, which makes it a good candidate for more specific studies towards Bi-based fluorescent materials. Moreover, it was detected that polymer 1 is more than twice as active against H. pylori as polymer 2. It can be concluded that there is an existing relationship between the structure and the antibacterial activity because the presence of chloride and triethylammonium ions in the structure of complex 2 reduces the antibacterial activity.

Series of complexes was prepared from some p‐block elements and indole‐3‐acetic acid (HIAA) as a plant hormone categorized from auxin class. Trivalent [Al(III), Bi(III)& Sb(III)] and divalent [Sn(II) & Pb(II)] ions, were used for complexation with indole‐3‐acetic acid. These complexes were analytically (elemental & EDX), spectrally (IR, Raman, UV‐Vis, SEM & XRD) and theoretically characterized. All complexes proposed having 1 : 2 molar ratio (M : L) through mono‐negative bi‐dentate binding mode. A tetrahedral geometry was proposed for Al(III) complex. While, the other complexes were suggested to be in distorted octahedral geometry due to presence of five bonds only and the sixth site inhabits by lone pair of electrons. Hirshfeld surface properties were obtained through Crystal explorer 3.1 software over structures oriented by VESTA package. The 3D‐crystals of Bi(III) and Sb(III) complexes displayed a noticeable red spots which point to the best contact site on their surfaces. Also, the conformational study reveals many physical characteristics that suggest the superiority of some complexes than the original ligand. Also, drug‐likeness outcomes clarify the lipophilic feature of Sn(II) and Pb(II) complexes. This feature may play a well bioactive behavior within living cells. Furthermore, pharmacokinetics as well as MOE‐docking simulation, were carried out versus 1lr5 & 3c6p proteins. Such proteins, were the co‐crystal forms of auxin‐class that act as hormone receiver inside plant cells. This study proposed the priority of Al(III), Sn(II) and Pb(II) complexes than the free hormone itself in the interaction with selected auxin proteins. We recommend these complexes for practical application in the field from specialist, they will improve the vital process within plant cells based on in‐silico results in this research.
