background : Coordination polymers are structures of different metal cent ere ligands bridge between the central metals. At the same time, in many cases, this linking role is compensated by various counterions or solvent molecules in addition to the organic ligand. Since each metal center is bound to more than one ligand, they create an endless arrangement of metal centers. Porous coordination polymers consist of an infinite and tight network of metal ions as anchors and ligands as connectors.
Aim : the synthesis and identification of new compounds of coordination polymer and application of these compounds in the elimination of cancer cells.
Methodlogy: in this study , six new coordination polymer complexes with mercury ( II ) and lead ( II ) and Ni ( II ) complexes were synthesized by two, hydrothermal , and sono chemistry methods .these complexes were characterized by FT-IR, XRD, TGA-DTA, and SEM techniques. .the structures of these complexes were characterized by x - ray diffraction and crystalography. The Hirshfeld surfaces of compounds crystal packing and the fingerprint maps were used to obtain data regarding non-covalent interactions. Conclusions: According to the analyses and studies conducted on the compound ([(µ2-Cl)(Ina)Hg(µ3-Cl)Hg(µ2-Cl)2(Ina)]n, this compound is a coordination polymer with coordination numbers of 5 and 6, which crystallizes in the monoclinic crystal system with the Pc space group. By examining the angles and lengths of the bonds around the central atom, an octahedral and square pyramidal geometric shape has been proposed for this compound. Intermolecular interactions in this structure have been investigated and the contribution of interactions in the structure has been measured, which are hydrogen bonds (O…H), H…Cl) and π-π interactions between aromatic rings in two molecules, which are the bonds forming aromatic rings, including; (C…H), (C…C) and (C…N) have the largest contribution among the non-covalent intermolecular forces in creati
