STUDIES ON COORDINATION-COMPOUNDS .8. SYNTHESES, STRUCTURAL, MAGNETIC, SPECTRAL AND THERMAL-PROPERTIES OF SOME COBALT(II), NICKEL(II) AND COPPER(II) COMPLEXES OF 2-AMINOPYRIMIDINE

The complexes bis ua(2-aminopyrimidine)-mu-sulphato-O,O'-cobalt(II)] d ihydrate (1), tena-[diaqua(2(2-aminopyrimidine))-mu-sulphatO-O', nicke l(II)I 2-aminopyrimidine (2), [pentaaqua (2-aminopyrimidine) nickel(II )] sulphate 2-aminopyrimidine (3) and 2(2-aminopyrimidine))-mu-sulphat o-O,O'-copper(II)] dibydrate (4) were prepared, structure determined b y X-ray methods and physical properties studied by magnetic, IR, NMR, EPR and reflectance methods. The thermal behaviour was studied by TG a nd mass spectrometric methods. The results are discussed on a structur al basis.
