One-dimensional arsenic-vanadium cluster chain bridged by two Co(en)(2) groups
The hydrothermal reaction of As2O3, V2O5, Co(Ac)(2), H3PO4, en and H2O produces [Co-II(en)(3)][{Co-II(en)(2)}(2)- (As6V15O42)-V-III-O-IV]. 4H(2)O, which consists of a one-dimensional arsenic-vanadium cluster chain bridged by two different geometries of Co(en)(2) groups. The interactions, which are established through hydrogen-bonding involving water molecules, the amine nitrogens, and terminal oxygen atoms, result in three-dimensional hydrogen-bonding network. Magnetic measurement indicates that the: overall magnetic behavior is weakly antiferromagnetic.
