英文摘要	The isostructural hexaaquatransition-metal/titanium citrate complexes (NH4)(2)[M(H2O)(6)][Ti(H(2)cit)(3)](2) center dot 6H(2)O [M(II) Mn 1, Fe 2, Co 3, Ni 4, Cu 5, and Zn 6] (H(4)cit citric acid), which were synthesized by reacting titanium(IV) citrate with divalent metal salts in the 1.0-3.5 pH range, adopt hydrogen- bonded chain motifs. The crystal structures feature three bidentate citrate anions that chelate to the titanium atom through their negatively charged alpha-alkoxy and alpha-carboxy oxygen atoms; the chelation is consistent with the large downfield shifts of C-13 NMR for carbon atoms for complex 6. The thermal decomposition of the complexes furnishes mixed metal oxides. The main-group magnesium analog when heated at 600 degrees C yielded MgTi2O5 that is of the pseudobrookite type; the particle size is approximately 30 nm. (C) 2007 Elsevier Inc.
