A hydrothermal reaction of NaVO3, Ce(NO3)3, H3BO3, 2,2′ bipyridine and water in a molar of 1∶2∶3∶2∶333 gives a yellow crystal [(C10H8N2)2VO2](H2BO3)·3H2O. It crystallizes in a triclinic with space group and unit...
Microporous heteropolyoxometalates Cs\-\%x\%H\-\{5-\%x\%\}PW\-\{10\}V\-2O\-\{40\}/SiO\-2 were synthesized by a sol\|gel technique and characterized by IR, UV\|Vis, BET adsorption/desorption isotherm. The structural fr...
Layered double hydroxide pillared by Paratungstate A ion, Mg 12 Al 6(OH) 36 (W 7O 24 )·4H 2O, was prepared via anion exchange reaction of the synthetic precursor, Mg 4Al 2(OH) 12 TA· x H 2O(TA 2- =terephthalate), an...
The novel amino acid containing polyoxometalate K 6[Cu(Ala) 2(H 2O) 2] 2[Cu 4(H 2O) 2\5(AsW 9O 34 ) 2]·16H 2O was synthesized from the reaction of K 10 [Cu 4(H 2O) 2(AsW 9O 34 ) 2]·20H 2O with β alanine. Its struct...
