Abstract
The synthesis, EPR characterization, and crystal structure of the title compd., are described. Crystals are triclinic, space group P?1, with a 9.6847(9), b 13.3123(13), c 17.1221(15) Å, ? 92.613(11), ? 90.303(11), ? 95.348(11)°; Z = 2, dc = 1.144; R = 0.068, Rw(F2) = 0.183 for 7920 reflections. The V atom is pentacoordinated by an oxo and two bidentate malonate ligands. The geometry around the metal is square-pyramidal and the two bidentate malonate ligands form the base of the pyramid. The V=O bond length is 1.556(3) Å and the range of V-O bond lengths is 1.960(3)-1.968(3) Å. The EPR spectrum (giso = 1.965 and Aiso = 0.00965 cm-1) is typical of a VIV system. [on SciFinder(R)]
