Popis: VO(VO3)6(VO(C10H8N2)2)2 has been synthesized by the hydrothermal reaction of V2O3 with 2,2′-bipyridine. The compound is monoclinic, space group P2 1 n (No. 14), a = 7.579 (2) A, b = 26.713 (8) A, c = 12.776 (3) A, β = 94.97 (2)°, Z = 2. Its structure consists of (VO3)n chains of corner-sharing pentavalent vanadium tetrahedra joined by V4+ square pyramids, with octahedral VO(C10H8N2)2 groups arrayed on the periphery of the chains. The V4+ sites are isolated magnetically, with the compound exhibiting Curie-Weiss behavior in the temperature range 10–300 K. The calculated μeff is 1.68 μ B V 4+ , close to the spin-only value.
