Synthesis and crystal structure of bis(2-aminobenzimidazolium) <i>catena</i>-[metavanadate(V)]
Аннотация
The structure of polymeric catena -poly[2-aminobenzimidazolium [[dioxidovanadium(V)]-μ-oxido]], {(C 7 H 8 N 3 ) 2 [V 2 O 6 ]} n , has monoclinic symmetry. The title compound is of interest with respect to anticancer activity. In the crystal structure, infinite linear zigzag vanadate (V 2 O 6 ) 2− chains, constructed from corner-sharing VO 4 tetrahedra and that run parallel to the a axis, are present. Two different protonated 2-aminobenzimidazole molecules are located between the (V 2 O 6 ) 2– chains and form classical N—H...O hydrogen bonds with the vanadate oxygen atoms, which contribute to the cohesion of the structure.
