Two novel isomeric complexes supported by vanadates {V4O12}: [{Cu(dpa)2}2V4O12] (dpa = 2,2′-dipyridylamine)
چکیده انگلیسی

Two Cu(II) complexes supported by tetravanadates, [{Cu(dpa)2}2V4O12] (1 and 2), have been synthesized under hydrothermal reactions. Structural analysis indicates that complexes 1 and 2 are isomeric and consist of a cyclic [V4O12]4-[V4O12]4- anion bridged to two [Cu(dpa)2]2+[Cu(dpa)2]2+ moieties. Close inspection of complexes 1 and 2 reveals that the [V4O12]4-[V4O12]4- anions adopt chair-like and boat-like configurations respectively, and are coordinated to each Cu(II) ions through a single terminal oxygen atom of two cross vanadium sites. Moreover, Complexes 1 and 2 exhibit trans- and cis-configurations, respectively.
