Synthesis of semiorganic material, triphenylphosphine oxide cadmium iodide (TPPOCdI), is reported for the first time. Employing the temperature reduction method, a crystal of size 16×7×6 mm3 was grown from dimethyl sulfoxide (DMSO) solution. Three dimensional crystal structure of the grown crystal was determined by single crystal X-ray diffraction study. The complex crystallizes in the chiral orthorhombic space group P212 121. FTIR study was carried out in order to confirm the presence of the functional groups. UVvisNIR spectral studies show that the crystal is transparent in the wavelength range of 2901100 nm. The microhardness test was carried out, and the load hardness was measured. Thermogravimetric and differential thermal analyses reveal the thermal stability of the crystal. Second harmonic generation efficiency of the powdered TPPOCdI, tested using Nd: YAG laser, is ～0.65 times that of potassium dihydrogen orthophosphate.

The standard molar enthalpy ΔrH0m of the reaction: MX2(s) + 2P(C6H5)3O(s) = MX2*2P(C6H5)3O(s), where M = Zn, Cd, Hg and X = Br, I (except HgI2) was obtained through the determination of the enthalpy of dissolution of the metal halides, ligand, and adducts in calorimetric solvent, giving the values: -(69.92 +/- 1.10); -(63.02 +/- 0.39); -(16.02 +/- 0.56); -(30.55 +/- 0.87); and -(16.48 +/- 1.14) kJ/mol, for the sequence of halides: ZnBr2, ZnI2, CdBr2, CdI2, and HgBr2.The standard molar enthalpies of formation were also determined: -(622.2 +/- 6.8), -(495.0 +/- 6.3), -(556.2 +/- 6.5), -(457.8 +/- 7.1), and -(411.1 +/- 6.4) kJ/mol, for the above sequence as well as the standard enthalpies of reaction: ΔdH0m for MX2*2P(C6H5)3O(s) = MX2(s) + 2P(C6H5)3O(g); and ΔlattH0m for MX2*2P(C6H5)3O(s) = MX2(g) + 2P(C6H5)3O(g).The mean enthalpy of dissociation of the metal-oxygen bond, (M-O), was also estimated and compared with other results.
