Influence of Aromatic Cations on the Structural Arrangement of Hg(II) Halides

“…These anions are discrete units without any significant interactions between them and surrounded by (2,2′-H 2 bipy) 2+ cations through N–H···I ionic associations (N (1)–H (1N)···I (2), 2.6524 Å and N (2)–H (2N)···I (1), 2.5764 Å) and weak C–H···I interactions, which form linear zigzag chains along the b axis (Figure b) (Table ). The Hg–I bond lengths (2.7398 (5)–2.8398 (5) Å) are within the range of reported (HgI 4 ) 2– anions (2.7430 (8)–2.844 (1) Å). − …”

“…In the three compounds, the monomeric Hg­(II) centers display a slightly distorted tetrahedral geometry ( 4 : τ 4 (Hg (1)) = 0.92; 5 : τ 4 (Hg (1)) = 0.91; 6 : τ 4 (Hg (1)) = 0.95) . The Hg–X bond lengths are within the range of reported (HgX 4 ) 2– anions ,− (Table ).…”

Bis[4-(trimethylammonio)phenyl] disulfide diiodide acetone solvate

“…Recently, we have engaged in the synthesis of metal complexes of the zwitterionic ammonium thiolate 4-(trimethylammonio)benzenethiolate (Tab) with different transition metals, such as Hg II , Au I and Ag I Chen, Zhang, Tang, Ren, Li et al, 2006;. The title compound, (I), represents an intermediate in the design of Tab (DePamphilis et al, 1974) and can be used as a large cation to form metal disulfides Chen et al, 2005). In order to investigate its properties further, the title compound was synthesized and characterized.…”
