The novel cesium chloride鈥?span class="smallcaps">d-ribose complex (CsCl路C₅H₁₀O₅; Cs-R) and cesium chloride鈥?i>myo-inositol complex (CsCl路C₆H₁₂O₆; Cs-I) have been synthesized and characterized using X-ray diffraction and FTIR, FIR, THz, and Raman spectroscopy. Cs⁺ is eight-coordinated to three chloride ions, O1 and O2 from one d-ribose molecule, O1 from another d-ribose molecule, and O4 and O5 from the third d-ribose molecule in Cs-R. For one d-ribose molecule, the oxygen atom O1 in the ring is coordinated to two cesium ions as an oxygen bridge, O2 is cocoordinated with O1 to one of the two cesium ions, and O4 and O5 are coordinated to the third cesium ion, respectively. O3 does not coordinate to metal ions and only takes part in forming hydrogen bonds. One chloride ion is connected to three cesium ions. Thus, a complicated structure of Cs鈥?span class="smallcaps">d-ribose forms. For Cs-I, Cs⁺ is 10-coordinated to three chloride ions, O1 and O2 from one myo-inositol molecule, O3 and O4 from another myo-inositol molecule, O5 and O6 from the third myo-inositol molecule, and O6 from the fourth myo-inositol molecule. One metal ion is connected to four ligands, and one myo-inositol is coordinated to four Cs⁺ ions, which is also a complicated coordination structure. Crystal structure results, FTIR, FIR, THz, and Raman spectra provide detailed information on the structure and coordination of hydroxyl groups to metal ions in the cesium chloride鈥?span class="smallcaps">d-ribose and cesium chloride鈥?i>myo-inositol complexes.
