摘要：

The acid-base behaviour of the N-2-(4-amino-1-methyl-5-nitroso-6-oxo-1,6-dihydropyrimidinyl)potassium L-alaninate (KL) and its reactivity with Ag(I), Cd(II) and Pd(II) metal ions have been studied. Three solid species with formulae AgL . 3H(2)O, CdL2. 6H(2)O and PdCIL . H2O have been obtained and characterized by IR, H-1 and C-13 NMR spectroscopic methods and thermal, conductivity and magnetic measurements. The structure of {Ag((eta(4)-mu(3)-L)]. 3H(2)O}(n) has been established by single-crystal X-ray diffraction and consists in a 3D-polymer, Within the polymer each Ag(I) ion is tetrahedrally coordinated to three differents L anions, while each ligand is coordinated in a rather unusual eta(4)-mu(3), coordination mode. Spectroscopic data show a similar coordination mode for the Cd(II) complex, while for the Pd(II) one a different coordination mode is proposed. (C) 1999 Elsevier Science Ltd. All rights reserved.
