- W2034272675 abstract "Abstract The adducts ZnX 2 ·2ur (X = Cl, Br, I), CdX 2 ·2ur (X = Br, I), CdX 2 · ur (X = Cl, Br, I) and HgX 2 ur (X = Cl, Br) have been characterized. The shifts of the stretching vibrations to low frequency ( v CO) and to high frequencies ( v CN and v NH) indicated that urea (ur) is oxygen-bonded to the metals. The standard molar enthalpies for the reaction MX 2 (c)+ n ur(c) = MX 2 · n ur(c) Δ r H m ⊖ were determined by solution-reaction calorimetry, given the following values: ZnCl 2 ·2ur(c), −59.72±0.30; ZnBr 2 · 2ur, −59.41±0.89; ZnI 2 · 2ur, −81.74 ±0.89; CdCl 2 · ur, −21.54±0.18; CdBr 2 · ur, −13.88±0.28; CdI 2 · ur, −30.75±0.36; CdBr 2 · 2ur, −24.40+0.21; CdI 2 · 2ur, −19.69±0.17; HgCl 2 · ur, −9.39±0.13 and HgBr 2 · ur, +1.00 ±0.78 kJ mol −1 . From these values, the standard molar enthalpies of formation (Δ f H m ⊖ ) and of decomposition (Δ D H m ⊖ ), and lattice enthalpy (Δ M H m ⊖ ) were calculated and the mean molar enthalpy of the metal-oxygen bond [t D (M-O)] was estimated. The thermochemical results indicate a decrease in stability of the adducts from zinc to mercury. The degree of hydrogen bonding affects differently the enthalpies of formation of adducts in solid state for urea and its derivatives." @default.
