摘要：

The distribution species and stability constants of the 4,6-dimethyl-2-thiopyrimidine (HL)/CdCl2 system have been determined by potentiometric measurements at 25 degrees C and 0.1 M KCl ionic strength. The solid complexes CdL(OH) and {[H(2)L]CdCl3}(n) were obtained and characterized by IR, H-1 and C-13 NMR spectroscopic and thermal techniques. In addition, the structure of the complex {[H(2)L][CdCl3]}(n) has been established by single-crystal X-ray diffraction. Crystals of the compound are orthorhombic, space group Pbca (No. 61) with cell constants a = 6.723(1), b = 17.624(4), c = 19.401(4) Angstrom, Z = 8, D-c = 2.080 g cm(-3). The structure was solved and refined to R = 0.055 (R(w) = 0.079) and consists of Cd(II) centres hexacoordinated by chloride ions in an octahedral arrangement. These octahedra are linked by opposite faces giving rise to infinite [CdCl3](n) chains which are bridged by H(2)L units through hydrogen bonds.
