A substituted porphyrinatoplatinum(II), meso-tetrakis(4-t-butylphenyl)porphyrinatoplatinum(II), has been spectroscopically and structurally characterized. The 1H NMR signal from the β-protons of the pyrrole ring is observed as a singlet with a full-width at half maximum of 1.6 Hz, contrary to the reported quasi-triplet resonance attributable to the 1H–195Pt long-range coupling. The porphyrin nucleus is nearly planar in the solid state. All macrocycle atoms lie within approximately 0.06 Å of the least squares mean plane with a pseudo-wave core conformation. The intramolecular Pt–N distances are 2.019(3) Å.
一种取代的
卟啉铂(II),即中-四(4-t-丁基苯基)
卟啉铂(II),已在光谱和结构上得到表征。从
吡咯环的β-质子中观察到的 1H NMR 信号是一个全宽半最大值为 1.6 Hz 的单重子,这与所报道的可归因于 1H-195Pt 长程耦合的准三重子共振不同。
卟啉核在固态下几乎是平面的。所有大环原子都位于最小二乘法平均平面约 0.06 Å 范围内,具有伪波核构象。分子内 Pt-N 间距为 2.019(3) Å。
