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

The reaction of PhHgOAc with 2-NCH(3)NCTPPH (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-NCH(3)NCTPP); 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-H(2,6) protons of 7 in CDCl(3) (0.01 M) at 599.95 MHz.
