2-D COSY and NOESY 1H NMR spectral studies on pyrazine-bridged dizinc(II)diporphyrin complex
摘要:
The dinuclear [Zn(TTP-m-O-(CH2)-)](2)(CH2) complex 1 (where TT-m-O = 5-(meta-hydroxyphenyl)-10,15,20-tritolylporphyrin dianion) coordinates axially nitrogen bases; pyrazine (Py) and pyrimidine. The solid 1 : 1 Py: 1 adduct has been isolated and identified as dinuclear complex (mu-Py) [Zn(TTP-m-O-(CH2) -](2)(CH2) 2 with pyrazine base bridging intramolecularly two zinc(II) metal ions based upon variable temperature 1-D and 2-D H-1 NMR spectral measurements.
