Dinuclear Mn(II), Ni(II), and Zn(II) complexes bridged by Bis(p-nitrophenyl) phosphate ion: Relevance to bimetallic phosphodiesterase

Article abstract of DOI:10.1246/bcsj.78.1072

2,6-Bis[N,N-di(2-pyridylmethyl)aminomethyl]-4-methylphenol (Hbpmp) has afforded dinuclear Mn(II), Ni(II), and Zn(II) complexes with two bis(p-nitrophenyl) phosphate (BNP^-) ions, [M₂(bpmp)(bnp) ₂]ClO₄ (M = Mn (1), Ni (2), Zn (3)). The structure of 1 · 2MeCN has been determined by the single crystal X-ray method. It has a dinuclear core structure bridged by the phenolic oxygen atom of bpmp^- and two BNP^- ions. Each metal center has a pseudo octahedral geometry with an average Mn-to-donor bond distance of 2.207 A. Physicochemical properties of 1-3 are studied and their relevance to biological phosphodiesterase is discussed.
