~(199)Hg NHR spectra of 18 Schiff base type arylmercury compounds have beenstudied.It was further confirmed that in the molecule of XC_6H_4CH=NC_6H_3-2-HgC1-4-CH_3there exists an intramolecular N→Hg coordination via a four-membered ring.For theseries of XC_6H_4CH=NC_6H_3-2-HgCl-4-CH_3(X is a para-or mera-substituent),there is agood linear correlation between δ~(199)Hg and Hammett’s o constants.The influence ofsubstituents of C-pheny1 ring on the δ ~(199)Hg can be explained in terms of theintramolecular N→Hg coordination.
H 199 NHg spectra of 18 Schiff base type arylmercury compounds have been identified. It was further confirmed that in the molecule of XC_6H_4CH = NC_6H_3-2-HgC1-4-CH_3there exists an intramolecular N → Hg coordination via a four-membered ring . For the series of XC_6H_4CH = NC_6H_3-2-HgCl-4-CH_3 (X is a para-or mera-substituent), there is agood linear correlation between δ ~ (199) Hg and Hammett’s constants. The influence of substituents of C- pheny1 ring on the δ ~ (199) Hg can be explained in terms of the intramolecular N → Hg coordination.
