THE SOLID COMPLEXES OF NI(II), CO(II), MN(II), AND CU(II) WITH 2-[(2-PYRROLYLMETHYLENE)AMINO]PHENOL AS A LIGAND

The complexes Cu(2)L(2) circle CH3COO, Mn(2)L(2) circle CH3COO, Ni(2)L (2) and Co(2)L(2), where L is 2-[(2-pyrrolylmethylene)amino]phenol (PY MAP). were synthesized and characterized by IR, UV/VIS and MS spectrom etry and by elemental analysis. IL has been found that PYMAP behaves a s a tridentate dianion or as bidentate menoanion and tridentate dianio n at the same time. which therefore forms various types of complexes. The Ni(II)- and Co(II)-PYMAP complexes form neutral chelates of M(2)L( 2) type, while the Mn(II)- and Cu(II)-PYMAP complexes have the same M( 2)L(2) stoichiometry but with acetate in the inner coordination sphere .
