Mercury(II) complex of inverted N-methylated porphyrin: HgPh(2-NCH3NCTPP)

The reaction of PhHgOAc with 2-NCH3NCTPPH (2) gave a mercury(II) complex of (phenylato)(2-N-methyl-5,10,15,20-tetraphenyl-21-carbaporphyrinato-N,N′,N″)-mercury(II), [HgPh(2-NCH3NCTPP); 7]; the coordination sphere around Hg(1) in 7 was a four-coordinate derivative with a seesaw geometry and dipole–dipole (DD) interaction governed the longitudinal relaxation rate for Hg(1)–Ph–H2,6 protons of 7 in CDCl3 (0.01 M) at 599.95 MHz.

The mercury phenyl complex bearing tridentate porphyrin ligand, N-methyl N-confused tetraphenylporphyrin, was prepared and its structure was established by X-ray crystallographic analysis.Figure optionsDownload as PowerPoint slide
