A novel three dimensional organic-inorganic hybrid based porous phase: Synthesis and characterization of reduced oxovanadium pyromellitate, [(V2O2)-O-IV(H2O)(2)(C6H2(COO)(4))]
Cevik, Sabri; Poyraz, Mehmet; Sari, Musa; Büyükgüngör, Orhan (Springer/Plenum Publishers, 2007)The hydrothermal reaction of a mixture of VOSO4 center dot H2O, 1,2,4,5-benzenetetracarboxylic acid (pyromellitic acid) and 0.1 M H2SO4 for 72 h at 160 degrees C gives blue needle like crystals of [V-IV stop O-2(2)(H2O)( ... -
Redetermination of the mixed-valence hexa-nuclear manganese oxide complex di-mu(4)-oxo-tetra-mu(3)-pivalato-hexa-mu(2)-pivalato-tetrakis(pivalic acid)dimanganese(III)tetra-manganese(II) at 100 K
Poyraz, Mehmet; Sari, Musa; Cevik, Sabri; Büyükgüngör, Orhan (Wiley-Blackwell, 2006)The structure of the title compound, [Mn-6(C4H9O2)(10)O-2(C4H10O2)(4)], has been redetermined at 100 K. The improved precision of the structure determination allowed the determination of the positions of the Mn-III atoms ... -
Synthesis and Characterization of Cis-[(VO)-O-IV(pzc)(2)(H2O)]center dot 2H(2)O (pzc: 2-pyrazinecarboxylate)
Cevik, Sabri; Sasmaz, Bihter; Poyraz, Mehmet; Sari, Musa; Büyükgüngör, Orhan (Springer/Plenum Publishers, 2011)Hydrothermal synthesis and the structural characterization of V(IV) complex of 2-pyrazinecarboxylate (pzc), is reported. The vanadium is in a distorted octahedral environment. Pairs of pyrazine-2-carboxylate ligands are ... -
Synthesis, structural, spectral, thermal and comparative biological activity studies of [V2O2(SO4)(2)(H2O)(6)]
Cevik, Sabri; Sasmaz, Bihter; Yenikaya, Cengiz; Colak, Ferda; Sari, Musa; Büyükgüngör, Orhan (Maik Nauka/Interperiodica/Springer, 2010)The hydrothermal reaction of a mixture of V2O5, VCl3, 2,5-pyridinedicarboxylic acid and diluted H2SO4 for 68 h at 180A degrees C gives a blue colored solution which yields prismatic blue crystals of IV (2) (IV) ...
