文摘
Reaction of in situ generated copper(II)-monosubstituted Keggin polyoxometalates and copper(II)-phenanthroline-oxalato complexes in ammonium or rubidium acetate buffers led to the formation of the hybrid inorganic-metalorganiccompounds E4[Cu(phen)(H2O)4]2[Cu4(phen)4(H2O)4(ox)3]0.6[Cu2(phen)2(H2O)4(ox)]0.4[Cu(phen)(ox)]0.8[{SiW11O39Cu(H2O)}2{Cu2(phen)2(ox)}]·20H2O [E: Rb (1), NH4 (2)]. The two compounds have been characterized by means ofelemental analysis, thermogravimetry, infrared and electron paramagnetic resonance spectroscopies, and magneticsusceptibility measurements, and their structures have been established by single-crystal X-ray diffraction. Bothcompounds are isostructural, and they contain a discrete bimolecular hybrid polyanion and several types of copper-phenanthroline complexes of variable nuclearity. The main structural features of these compounds are the presenceof the new hybrid POM [{SiW11O39Cu(H2O)}2{Cu2(phen)2(
mages/entities/mgr.gif">-ox)}]10-, where the dinuclear copper-oxalato complexis sandwiched by two copper-monosubstituted POMs, and the coexistence of five different copper-phenanthrolinespecies with nuclearities ranging from one to four.
