(Blackwell Publishing, 2006)asymmetric unit of the title compound, [Mn-3(C5H9O2)(6)O(C5H5N)(2)(C5H10O2)], comprises two independent and similar [(Mn2MnO)-Mn-III-O-II{(CH3)(3)CCO2}(6)(py)(2)(CH3)(3)CCOOH] (py = pyridine) molecules each with an ... -
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 ... -
