Heterometallic Copper-Vanadium Compounds: Crystal Structures of Polymers [Cu(im)4(V2O4(mand)2)] n and [Cu(im)4(V2O4((S)-mand)2)] n ·2nH2O (im = imidazole, mand = mandelato2-).

The polymeric structures of two new vanadium-copper heterometallic complexes are constructed from [Cu(imidazole)4]2+ cations that are coordinated to two terminal oxido ligands of [V2O4(mandelato)2]2- anions with different orientation of the phenyl groups depending on the chirality of the mandelato ligand.
