Sinteza şi studiul cu raze X a unui nou compus al Cu(II) CU 1,3-BIS(4-Piridil)Propan

Abstract

Coordination polymers (CPs) are attractive through diverse structures and application patterns, mainly determined by the characteristics of inorganic and organic building units. However, in order to understand the influence of ligands on the molecular geometry of the CPs, it is necessary to accumulate structural data on the series of compounds by performing a comparative analysis. The ligands with –(CH2)n– (n = 1, 2,...) contribute to the formation of coordination polymers, providing additional flexibility for the connection between metal and ligand. So far, a number of flexible ligands bearing –(CH2)n– moieties have been applied for the construction of CPs to give diverse supramolecular networks. The coordination polymer [Cu(bpp)2(H2O)]n(BF4)2n·ndmf·0.75nH2O where bpp – 1,3-bis(4pyridyl)propane was synthesized, and X-ray study of the composition and crystal structure was undertaken. Analysis found that 24.7% of the crystal volume of the studied polymer constituted cavities, indicating the probability of adsorption properties.
