(4,4,-H2bipy)4[Cu(4,4'-Hbipy)2(4,4,-bipy)(P2W_(18)O_(62))2]-7H2O: A New Supramolecular Hybrid Based on 1D Cu-N Coordination Polymeric Chain and Wells-Dawson Type Polyoxometelate

摘要

The hydrothermal reaction of CuCl2·2H2O with K6P2W_(18)O_(62)·15H2O and 4,4'-bipyridine (4,4'-bipy) gave a novel inorganic-organic hybrid (4,4'-H2bipy)4Cu(4.4'-Hbipy)2(4,4'-bipy)(P2W_(18)O_(62))2]·7H2O, in which Cu(II) coordinated to [P2W_(18)O_(62)]~6 polyanions, 4,4'-bipydine and monoprotonated 4,4'-bipyridine ligands to form a 1D polyanionic chain. The 1D polyanionic chains stacked into a 3D supramolecular architecture consisting of numerous 1D open channels, in which water molecules are encapsulated. Additionally, thermal stability of the inorganic-organic hybrid materials has also been studied.
