Structure and biological profile of transition metal complexes with (E)-4-(2-(pyridin-2-ylmethylene)hydrazinyl)quinazoline.

The interaction of the recently reported quinazoline derivative (E)-4-(2-(pyridin-2-ylmethylene)hydrazinyl)quinazoline (L) with a series of metal(II) (= copper(II), nickel(II), cobalt(II) and cadmium(II)) chlorides or nitrates resulted in the formation of mononuclear complexes which were characterized by spectroscopic techniques and single-crystal X-ray crystallography, i.e. [Cu(L)]Cl·4HO (1·4HO), [Ni(L)]Cl·4HO (2·4HO), [Ni(L)](NO)·MeOH (3·MeOH), [Co(L)]Cl·4HO (4·4HO), [Co(L)](NO)·HO (5·HO), [Co(L)](NO)·2.
