Elaboration, structural, thermal and vibrational studies of two new cadmium hybrid compounds:: [Cd(OH)2[O2C(CH2)2CO2], and [Cd3(OH)2][O2C(CH2)2CO2]2

Two new cadmium hybrid inorganic-organic compounds have been hydrothermally prepared and structurally characterized using single-crystal X-ray diffraction. [Cd(OH)](2)[O2C(CH2)(2)CO2] ([CD1]) is Monoclinic P2(1)/c, a 10.12(2) angstrom, b = 5.554(5) angstrom, c = 6.134(3) angstrom, = 96.24(8)degrees and z = 2. [Cd-3(OH)(2)][O2C(CH2)(2)CO2](2) ([CD2]) is Orthorhombic Pcca, a 10.657(2) angstrom, b = 6.8610(3) angstrom, c = 16.949(3) angstrom, and z = 4. Both [CD 1] and [CD2] have bi-dimensional inorganic networks pillared by carbon atoms of the succinate anions. [CD I] inorganic moiety is composed of a double layer of equivalent CdO6 octahedra sharing corners or edges. Smoothly corrugated mono-layers of CdO6 octahedra sharing corners or edges are present in the [CD2] inorganic moiety. Thermal as well IR spectroscopic studies are also presented. These hybrid compounds are stable up to 400 degrees C under air flow. (c) 2005 Elsevier SAS. All rights reserved.
