Abstract
A new decavanadate compound V10O28[Co(H2O)6]3(C8H18O6N2S2)2 (I) is synthesized and characterized by single crystal X-ray diffraction, thermogravimetric analysis, FT-IR spectroscopy, and scanning electron microscopy. The sizes of the monoclinic unit cell are as follows: a = 13.2851(16) Å, b = 22.769(3) Å, c = 13.1883(16) Å, β = 117.555(2)°, V = 3536.7(7) Å3, C2/m space group, Z = 2. The studies revealed that different moieties in the compound show a three-dimensional framework structure, in which {CoO6}, the decavandate cluster anions, and 1,4-piperazinediethanesulfonic acid (PIPES) interact with each other by intermolecular forces and strong hydrogen bonding. Bond valence calculations were used to calculate the valence states of the atoms.
