Elaboration et caractérisation par diffraction des rayons X de nouveaux polymères de coordination à base de cuivre (II).

Abstract

This work falls within the scope of the synthesis and structural resolution of new polymers based on copper (II). It is {[Cu2 (C2O4) 2 (H2O) 2] 3H2O)]}n and {[Cu1.5 (NO2C4H9) 4Cl2 (H2O) 2] ClO4}n. The first crystallizes in the triclinic system with space group P-1. This polymer forms a one-dimensional chain following [101]. It is generated by interdimère and intradimère interactions. The cohesion of the structure is ensured by a three- dimensional network of hydrogen bonds of medium type OH ... O.The secand crystallizes in the system monoclinic with the space group P21 / a. this structure is ionic, it forms a one-dimensional chain along a. this polymer is generated by interdimère and intradimère interactions. The cohesion of the structure is ensured by a three-dimensional network of hydrogen bonds of type N-H ... Cl and N-H ... O, OH ... O, C-H ... Cl, C-H ... O.
