A Heterobimetallic 2-D Coordination Polymer [Na2(Cu2I2(2pyCOO)4)(H2O)4]n (2pyCOO−=picolinate) within a 3-D Supramolecular Architecture

Abstract

Abstract:A heterobimetallic 2-D coordination polymer, [Na 2 (Cu 2 I 2 (2pyCOO) 4 )(H 2 O) 4 ] n (1) (2pyCOO=picolinate) was synthesized and characterized. The complex was also structurally characterized using single X-ray diffraction studies that revealed the complex 1 having a vertex symbol of 4.8 2 which corresponds to fes topology. Together with hydrogen bonds and interdigitating π···π interactions, these thus facilitate the formation of 3-D supramolecular network. The nitrogen gas absorption amount of 1 at 77 K shows a small volume of N 2 sorption isotherm with a small Langmuir and a Brunauer-Emmett-Teller (BET) surface area indicating that the heterobimetallic 3-D supramolecular of 1 exhibits a very weak ability of adsorbing gas.

Synthesis, Crystal Structures, and Properties of Two Coordination Polymers Built from Imidazolyl and Carboxylate Ligands

“…The structure design methodology and properties of coordination polymers are mainly dependent on the intrinsic organic linkers [9,10], inorganic metal units, as well as the external synthesis conditions such as reaction temperatures, pH of the medium, reaction solvents, and counter anions [11][12][13]. Generally, organic linkers with N and/or O donors have often been utilized as effective building units in the process of coordination polymers [14,15].…”
