Thermal studies on metal complexes of 5-nitroso-pyrimidine derivatives

III. Thermal behaviour of Hg(II) complexes of 6-amino-5-nitrosouracil derivatives

Journal of Thermal Analysis and Calorimetry
Authors: M. Moreno-Carretero and J. Salas-Peregrín

Four Hg(II) complexes, containing as ligands 6-amino-5-nitrosouracil (AH), 6-amino-3-methyl-5-nitrosouracil (BH) or 6-amino-1-methyl-5-nitrosouracil (CH), have been synthesized and their thermal behaviour studied by TG and DSC techniques: Hg3Cl6(AH)4, HgCl2(BH)2· 2 H2O, HgCl2(BH)2 · H2O and HgC2· 2 H2O.

Thermal studies on metal complexes of 5-nitrosopyrimidine derivatives IV

Complexes of Fe(II), Co(II), Ni(II) and Cu(II) with 6-amino-5-nitrosouracil

Journal of Thermal Analysis and Calorimetry
Authors: J. M. Salas-Peregrin, M. A. Romero-Molina, M. A. Ferro-Garcia, and M. N. Moreno-Carretero

The thermal decomposition processes of the complexes of 6-amino-5-nitrosouracil with Fe(II), Co(II), Ni(II) and Cu(II) have been studied using TG and DSC techniques. Dehydration energies have been calculated from the DSC curves.

Tetrachloroaurates of 8-ethyl-, 8-isopropyl-, 8-propyl- and 8-pentyltheophylline were synthesized and studied by1H-NMR, TG and DSC techniques. The metal is not coordinated to the 8-alkyltheophylline derivatives and forms a salt-like structure.

I. Thermal behaviour of Zn(II) complexes of 6-amino-5-nitrosouracil derivatives

Journal of Thermal Analysis and Calorimetry
Authors: M. N. Moreno-Carretero, J. M. Salas-Peregrín, and A. Mata-Arjona

The following Zn(II) complexes of deprotonated 6-amino-5-nitrosouracil (AH), 6-amino-3-methyl-5-nitrosouracil (BH) and 6-amino-1-methyl-5-nitrosouracil (CH) have been prepared and their thermal behaviour studied by TG and DSC techniques: ZnA2(H2O)2, ZnB2 · 4 H2O, ZnC2 · 4 H2O and ZnC2(H2O)2 · H2O. The values of the dehydration enthalpy of the complexes are in the 31.3–76.5 kJ mol−1 H2O range and, except in the first complex, the dehydration processes take place in several steps. The pyrolysis of the complexes finishes between 540 and 725° C ZnO remaining as residue.
