The sol id complexes of Ni (II), Co(II), Mn (II) and Cu (II) with 2‐ [(2‐pyrrolylmethylene) amino] phenol as a Ligand

The complexes Cu₂L₂°CH₃COO, Mn₂L₂ ^°CH₃COO, Ni₂L₂ and CO₂L₂, where L is 2‐[(2‐pyrrolylmethylene) amino] phenol (PYMAP), were synthesized and characterized by IR, UV/VIS and MS spectrometry and by elemental analysis. It has been found that PYMAP behaves as a tridentate dianion or as bidentate monoanion and tridentate dianion at the same time, which therefore forms various types of complexes. The Ni (II)‐ and Co (II)‐PYMAP complexes form neutral chelates of M₂L₂ type, while the Mn(II)‐ and Cu (II)‐PYMAP complexes have the same M₂L₂ stoichiometry but with acetate in the inner coordination sphere.

Key words:

• 2‐[(2‐pyrrolylmethylene) amino] phenol
• complexes
• MS
