| 英文摘要 | The barium ethylenediaminetetraacetato (edta) complexes, ba-2(edta) and ba-2(edta)center dot 2.5h(2)o, were hydrothermally synthesized and characterized by single-crystal x-ray structure determination. ba-2(edta) (monoclinic, p2(1)/c, (no.14), a = 9.7651(10) angstrom, b = 8.0870(6) angstrom, c = 10.3313(11) angstrom, beta = 118.024(4)degrees, v = 720.20(12) angstrom(3), z = 2) exhibits a layered arrangement of coordination polyhedra around barium whereas in the crystal structure of ba-2(edta)center dot 2.5h(2)o (tetragonal, p4nc, (no.104), a = 19.7126(7) angstrom, c = 8.9813(4) angstrom, v = 3490.0(2) angstrom(3), z = 8) a completely different three dimensional framework containing wide channels is formed. thermoanalytical investigations reveal a reversible dehydration behavior for ba-2(edta)center dot 2.5h(2)o. the anhydrous form was characterized by pxrd (tp, a = b = 19.226(10) angstrom, c = 8.986(3) angstrom, v = 3335.4(3) angstrom(3)) and is assumed to be closely related to the crystal structure of the hydrated starting material. the final decomposition product of both compounds after heating in air up to 1000 degrees c was found to consist of pure baco3. |
