Bimetallic copper–vanadium mandelato complexes with bpy and phen as ancillary ligands. 51V NMR spectra of vanadates in DMSO

Popis výsledku v původním jazyce

Two novel heterometallic complexes [Cu(bpy)2V2O2(O2)2(R-mand)2][Cu(bpy)2V2O2(O2)2(S-mand)2]·2CH3CN·2H2O (1), and [Cu(phen)2V2O2(O2)2(R-mand)2][Cu(phen)2V2O2(O2)2(S-mand)2]·2CH3CN·2H2O (2), (mand = mandelato(2–) = C6H5CH(O)CO22–) were prepared and characterized by spectral methods. X-ray single-crystal analysis revealed the difference between both structures. While 1 contains a bonding copper(II) and vanadium(V) atoms through the bridging oxygen atom Cu–O–V, the metallic atoms are connected in 2 through the carboxylic group CuOCOV. Complexes 1 and 2 are immediately decomposed in their aqueous solutions, but their integrity is preserved for some time in DMSO. 51V NMR spectra of DMSO solutions of vanadates(V), peroxidovanadates(V) and vanadium(V) mandelato complexes are presented for the first time.
