摘要

Two novel heterometallic complexes [Cu(bpy)(2)V2O2(O-2)2(R-mand)(2)][Cu(bpy)(2)V2O2(O-2)2(S-mand)(2)]. 2CH(3)CN center dot 2H(2)O (1), and [Cu(Phen)(2)V2O2(O-2)(2)(R-mand)(2)][Cu(Phen)(2)V2O2(O-2)(2)(S-mand)(2)].2CH(3)CN.2H(2)O (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 Cu-O-C-O-V. Complexes 1 and 2 are immediately decomposed in their aqueous solutions, but their integrity is preserved for some time in DMSO. V-51 NMR spectra of DMSO solutions of vanadates(V), peroxidovanadates(V) and vanadium(V) mandelato complexes are presented for the first time. (C) 2019 Elsevier Ltd. All rights reserved.
