COORDINATION-COMPOUNDS OF 6-PROPYL-2-THIOURACIL WITH MERCURY DIHALIDES

Coordination compounds of 6 propyl-2-thiouracil (PTU) have been prepared and analytically and spectroscopically characterized. The reactions in acetonitrile in the molar ratio 1/1 produce complexes of the type HgX2(PTU) where X = Cl, Br or 1. They are non electrolyte in acetonitrile and their IR and Raman spectra indicate that they possess a dimeric halogen-bridged structure Of C2h molecular symmetry. The reactions in the ratio ligand/HgX2 = 2/1 yield compounds of the type HgX2(PTU)2 for which the vibrational spectra show that they possess a pseudotetrahedral structure of C2v molecular symmetry.
