Bis[N-(4-nitrophenyl)thiobenzamidato]mercury(II)

Abstract

The molecule of the title compound, [Hg(C(13)H(9)N(2)O(2)S)(2)], has approximate twofold rotation symmetry, with the Hg atom in an essentially linear two-coordinate HgS(2) environment supported by secondary pi interactions with the nitrophenyl rings of both ligands. The ligands are in the imine-thiolate rather than the amine-thione tautomeric form.

Synthesis and crystal structure of bis[N-(phenyl)-3,5-dinitrothiobenzamidato]mercury(II) and bis[N-(phenyl)-4-nitrothiobenzamidato]mercury(II)

“…Hg-S bond distances are similar in the [Hg(bztzS) 2 ] complex [2.348(3) and 2.344(3) Å ][13]. The Hg-S(1)-C(7) and C(7)-N(1)-C(1) angles are 104.47(2) and 123.02(3) in 1, slightly smaller than reported for [Hg(Nnptb) 2 ][14]. The dihedral angle between C1-C6 and C8-C13 rings is 77.82 .…”

“…A similar bis-3 arrangement has been observed in the closely related [Hg(nptb) 2 ] (nptb ¼ N-(4-nitrophenyl)thiobenzamidato) [14], although here the molecule has approximate C 2 rather than exact inversion symmetry. Hence, the two benzene rings are not exactly parallel and have slightly different distances to Hg (closest Hg Á Á Á C ¼ 2.979-3.319 Å and 3.008-3.279 Å ), and the S-Hg-S linkage is not strictly linear (174.37 ).…”
