Hydrothermal synthesis of two Anderson POM-supported transition metal organic–inorganic compounds

Ligand mediated valence fluctuation of copper in new hybrid materials constructed from decavanadate and a Cu(1,10-phenanthroline) complex

“…Moreover, the presence of two nitrogen atoms on the condensed ring increases the basic nature which leads to greater and easier donation of the lone pairs of electrons to the central ion, thereby stabilizing the complex. Among the large number of hybrid materials that have been reported based on polyoxometalates (POMs) and 1,10phen, 10,11,[24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] there are so far only two reports on decavanadate and 1,10-phen to the best of our knowledge: [Fe( phen) 3 ] 2 • [V 10 O 28 ]•15H 2 O, synthesized under hydrothermal conditions, 10 and [CuCl( phen) 2 ] 3 H 3 V 10 O 28 •7H 2 O, synthesized by the solution method. 11 The solution chemistry of the isopolyvanadate ion as well as the condensation power of the protonated isopolyvanadate ion are strongly dependent on the media environment such as † Electronic supplementary information (ESI) available: Crystallographic information file (CIF), the atomic coordinates and equivalent atomic displacement parameters, anisotropic atomic displacement parameters and important bond lengths.…”

Synthesis and Characterization of New Anderson-Type Polyoxometalates: [M((1,10-phen)(OH)x]3[Cr(OH)6Mo6O18]·16H2O (M=Cr, Mn, Co, Ni, Cu; x=1,2)

“…Shi and coworkers have been successfully synthesized compounds based on the [Cr(OH)6Mo6O18] 3-and lanthanide ions (21)(22). [Cu(phen)]2[CrMo6H5O24] has been hydrothermally synthesized (23). (H3O)[(3-C5H7N2)2(Cr(OH)6Mo6O18)]•3H2O was also hydrothermally synthesized and showed high catalytic activity for oxidation of acetone (24).…”

Synthesis and Characterization of Ammonium Potassium Tellurium Polyoxomolybdate: (NH4)2K2TeMo6O22·2H2O with One-Dimensional Anionic Polymeric Chain [TeMo6O22]4−

“…The later crystallizes in the [Mo 6 Te 2 O 24 ] 4− zerodimensional aggregates composed of one hexamolybdic Mo 6 O 18 and two discrete TeO 3 units. Anderson-Evans polyoxometalates (POMs) containing heteroatom tellurium are known as one of the pioneering POM archetypes, which usually exist as a discrete [TeMo 6 O 24 ] 6− cluster in the crystal structures [20][21][22][23][24][25][26][27][28][29][30]. Polyoxometalates with one-dimensional chain-like, two-dimensional layer-like, or three-dimensional anionic extended framework structures are relatively rare.…”
