Abstract

The new complex [H2Pipz][VO2(dipic-OH)]2·2H2O (1), where H2dipic-OH = 4-hydroxypyridine-2,6-dicarboxylic acid and Pipz = piperazine, was synthesized and characterized by elemental analysis, FTIR, 1H NMR, 13C NMR and UV-Vis spectroscopy and single crystal X-ray diffraction. The crystal system is triclinic with space group Pi¯. In this compound, piperazine is diprotonated and acts as counter ion.
