Hydrothermal synthesis and characterization of a novel one-dimensional titanium glycolate complex single crystal: Ti(OCH2CH2O)(2)

Single crystals of a novel titanium glycolate complex, Ti(OCH2CH2O)(2), hav e been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, IR spectroscopy, thermal analysis (TG-DTA), and scanning elec tron microscopy (SEM). The titanium glycolate complex crystallizes in the m onoclinic space group C2/c (no. 15), with unit cell parameters of a = 15.20 4(9) Angstrom, b = 7.568(2) Angstrom, c = 5.816(6) Angstrom, beta = 110.87( 6)degrees, Z = 4, R = 0.036, and R-w = 0.033 for 598 reflections (I > 3 sig ma(I)) and 43 variables. The structure is described as parallel chains buil t up from edge-sharing Ti4+O6 octahedra. The six oxygen atoms are offered b y four ethylene glycolate ligands. Each ethylene glycolate ligand bridges t wo titanium atoms with one of its oxygen atoms, and the other is terminal.
