Hydrothermal synthesis and crystal structure of a one-dimensional ladder-like chain complex [V4vO10(phen)2]

An organic-inorganic hybrid vanadium oxide [(V4O10)-O-v(phen)(2)] has been hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction. Red-brown crystals crystallize in the triclinic system, space group P (1) over bar a = 9.782(2), b = 6.5124(14), c = 19.765(4) Angstrom, alpha = 89.94(2)degrees, beta = 100.66(2)degrees, gamma = 89.86(2)degrees, V= 1237.4(4) Angstrom(3), Z = 2, lambda(MoKalpha) = 0.71073 Angstrom (R(F) = 0.0302 for 4342 reflections). Data were collected on a Siemens P4 four-circle diffractometer at 293 K in the range of 2.10 < 0 < 25.02degrees using the omega-scan technique. The title compound, a non-mixed-valence hybrid tetravanadate, exhibits an infinite one-dimensional ladder-like chain with organonitrogen donors of phen ligands coordinated directly to the vanadium oxide framework, where the octahedral {VO4N2} and tetrahedral {VO4} building blocks are linked by corner-sharing oxygen atoms.
