Structural, Spectroscopic and Thermal Characterisation of bis (dibenzoylmethanato)Cd(II) Adducts with Dimethylsulfoxide and Water

Adducts of cadmium(II) dibenzoylmethate, Cd(dbm)2X2 (X = DMSO, H2O) were synthesized and analyzed by thermogravimetric analysis (TGA), differential-scanning calorimetry (DSC), hot-stage microscopy (HSM), single crystal X-ray diffraction, FTIR and Raman spectroscopy, and elemental analysis. Products obtained by thermal decomposition of the two Cd(II) complexes in oxygen, were used for quantitative analysis of cadmium in the adduct molecules. Single-crystal X-ray diffraction analysis of the DMSO adduct revealed that it has cis configuration. The DMSO adduct crystallizes in P21/a space group, a = 17.2494(6) Å ; ; ; , b = 8.3251(4) Å ; ; ; , c = 22.2746(9) Å ; ; ; , β = 93.836(3)°, V = 3191.53(7) Å ; ; ; 3, Z = 4.
