Hydrothermal Synthesis and Crystal Structure of a Novel Two-Dimensional Vanadium Oxide Complex with a 6,14-Net Sinusoidal Ruffling Anionic Layer: [Ni(phen)2V4O11] (phen = 1,10-Phenanthroline)

Two novel vanadium oxide nickel(II) complexes, Ni(phen)2V4O11 (1) and [Ni(phen)2]2V6O17 (2) (phen = 1,10-phenanthroline), are synthesized hydrothermally. 1 has a unique two-dimensional layer constructed from the 6,14-net sinusoidal ruffling anionic layer (V4O11)n2n- and covalently bonded Ni(phen)2 fragments.
