| heal.abstract | The reaction of 2-mercapto-3,4,5,6-tetrahydro-pyrimidine (tHPMT) or 2-mercaptopyrimidine (PMTH) with hydroiodic or hydrochloric acids in the presence or absence of di-iodine in dichloromethane solutions resulted in the formation of complexes with formulae [2{(tHPMT)22+} 2(I�) (I42�)] (1), [2{(tHPMT)22+} Cl� 3(I3�)] (2), [6{(tHPMT)22+} 3(Cl�) 2(I�) 5(I3�)] (3) and [2{(PMTH2)+} I42�] (4). The compounds were characterized by FT-IR, and Raman spectroscopic techniques. The crystal structures of 1-4 were also determined by X-ray diffraction. Complexes 1 and 4 contain tetra-iodides di-anions (I42�) as counter parts. The linear geometry of tetra-iodides species is broken in case of 1 and the deviation from the linearity for this di-anion is greater than in any such molecule described thus far. Moreover in complex 3 with a hexa-iodide di-anion, (I62�) is detected by considering the distance of 3.67 Å as a bonding interaction. | en |
